If you have a late model Gamo with a plastic trigger
and safety, the GRT-III trigger will not work. If in

A different gun
Hello Charlie,
It's amazing it took only 11 days for the triggers
to get to me here in Australia . On opening the
envolope I was very impressed at the look and finish
of your product.. I left them sitting there for an
hour or so them I couldn't resist I had to install
it at least on one of my air rifles.. I decided il
install it on my gamo shadow fox as it is only one
week old .. It took me only five minutes to install
your fine piece of work.. once again couldn't help
myself had to try it and I was amazed that taking
the factory trigger out and droping your trigger in
makes it a totaly diffrent gun.
I
set up a target 15 meters away and all five shots
were very accurate all of them touching each other.
AMAZING!! I would recomend this trigger to anyone or
should I say anyone with an air rifle should have
this trigger.... It's not worth shooting if you
haven't got one of charlies triggers! It should be
made a law to have this trigger... I can't wait to
put the other one on my gamo hunter 440 in .22.
Thank you Charlie..

Holy Crap
Charlie,
I received the trigger two days ago, thank you! I
installed it today and it is like you said, it took
me less than 3 minutes to put the new trigger in but
more like 20 minutes trying to figure out how to get
the gun back together after dropping bushings and
spacers out while disassembling the rifle, LOL . But
now here is where I have to say......wholly crap
Batman!
What a difference in the trigger pull! It's like
3/4th's less of a pull than the original. It's very
light and crisp. And wow, what a difference it made
in accuracy! I can now squeeze off a shot and not
jerk the gun due to a hard trigger pull from the old
trigger. I am shooting at 15 yards to start and
actually getting the shots touching one another. I
ran out of daylight while shooting so I have to wait
until tomorrow to sight the rifle in for 25 yrds and
am excited to see the results due to the new
trigger. Thank you again for your recommendation!

Bob,
Here's my take on the trigger. Feel free to use it
as you see fit.
I have shot every kind of gun imaginable. I have
done tons of trigger jobs to my firearms. All I can
say is "WOW". I have spent 200+ dollars on "match
grade" trigger units in "real" guns and airguns too
and for a little more than a 10th of the price this
trigger is unbelievable! The tech support is second
to none. Emails with links to directions and
installation videos. Not to mention your phone
conversations with me. I want to go buy another gun
just to work on the trigger!!!!!
THANKS !

Hi Bob,
I received your GRT III trigger today and installed it, which was easier than
I thought it would be. The original trigger pull was
long, somewhat heavy, and gritty. The GRT III trigger pull is short, light and very smooth. The
GRT III fit in my Benjamin Trail very well, and
allows me to place one pellet on top of the next at
10 yards. Thank you Bob for another fabulous
trigger! Sincerely, John Schrader
P.S. The GRT III is an awesome looking trigger as
well and adds a lot to the visual appeal of my air

Astounding
ASTOUNDING!!!!!!! That's a word I've never used on
any purchase that I've ever made, until now.
I
am truely amazed. I knew that the GRT III would be a
major improvment to my Gamo Viper, but the GRT III
totally exceeds any expectations that I ever could
of imagined.
Before the GRT III, it was impossible to shoot
consistantly with the excess trigger travel and
heavier pull weight of the stock trigger.
After an easy 10 minute installation, I shot several
1/4" groups at 30'.
Then I started shooting at thumb tacks, also at 30',
these tacks were only 1/8th" across the head, after
hitting 3 in a row, I put the Viper up, totally
satisfied that I have made one of the best purchases
in my 54 years of life and that I can totally hang
with anyone, anytime, anyplace on any firing line

Your Trigger
Hi
Charlie,
I just received you trigger and installed it. This
is the first air rifle that I have had as an adult.
I am 58 now. Years ago I did a lot of hunting and
did a lot of work on my rifles. I had several
varmint rifles as well as deer rifles. I would not
keep one unless I could cover 100yd groups with a
quarter. Some good rifles had decent adjustable
triggers but I would buy aftermarket triggers on
some. I had used several brands of triggers usually
Timery (not sure about the spelling) but to my
point. I NEVER SPENT $32 that made such a
difference. To me nothing is more important than a
trigger on a fire arm or in this case an air rifle
to improve performance. The one that came with the
Remington Vantage 1200 was junk. I have just fired
a few rounds since I changed it but what a
difference.
Thank You So Much!
Jim

Installed your trigger
Good morning Sir. I received and installed your
trigger yesterday.
First thing that comes to mind is amazing. The speed
that it got here was impressive and it was very easy
to install. I read the directions twice before
receiving the trigger and read a link on Pyramid Air
and was prepared for install when it got here. Took
about 20 minutes only because I almost forgot the
bushing that rolls on the inside of the stock so I
had to take the stock off again. No adjustments
needed once installed.
Took it out to the garage for trial. The new trigger
is very light compared to stock so first round was a
flier but still on the target. After about 10 shots
to get the feel of the trigger I was shooting 3 shot
groups that could be covered by 1 pellet! The
picture is attached. I am amazed at the difference
the trigger makes. Looks and feel are very nice. By
far the best upgrade to the gun and the least
expensive. Directions were very clear and easy to
follow. Lubed the trigger and all points internal
like suggested. This is an outstanding upgrade and
highly recommended. I cannot wait till this weekend
so I can really stretch my rifle out and see what it
can do.
Your website, service and trigger's are top notch.
Thank you.

Hi Charlie
i'm jim from italy , just wanted to say that the GRT
TRIGGER has arrived . i have installed it and wow
what a differnce it makes . I’m so pleased to have
made the purchase now. i read the comments before i
decided to purchase it and said now that i read the
comments I’m sure that the first shot wont be a miss
, but as i stood aiming at the target well as all
the others has stated the first shot was unexpected.
the trigger is so soft and smooth i didn't even
realize that i just have taken the shot. and as to
say it wasn't as planed . The trigger was so smooth
that i shot before i was ready . there are no words
to explain the new trigger. the gold finish makes
the rifle look even more serious that before and
well as for the rest (as I stated before I’m
wordless ) for all those that have the old Gamo CFX
believe me that it's a whole new ball game with the
GRT TRIGGER.
THANKS CharlieDaTuna . YOURE UPGRADE IS A PIECE OF

I
received your trigger in the mail today...fast
processing and quick mail.
I
am totally pleased with the change it makes in my
Gamo CFX. I expected the stock trigger to be mushy
and not too good, but I was surprised at how mushy
it is. I shot about 200 rounds with the stock
trigger so I would have a chance to get used to it
and have a good bench mark starting point.
Where the stock CFX trigger started makes the
transformation as a result of the 10 minute (I timed
it) installation of the GRT III all the more remarkable. I am totally pleased with
the new trigger feel and consistency, I know
exactly when it is going to let off and I don't have
to pull it halfway to the butt plate. It makes the
gun an absolute pleasure to shoot. This consistency
seems to have enabled me to shrink my 20 yard groups
from quarter size to dime size with occasional
cloverleafs and I think we can do better, I just ran
out of the gun's favorite pellets.
As all the reviewers have said your trigger design
makes a pretty good airgun into a great airgun. You
can be sure I'll be buying a GRT III on every
compatible airgun I buy.

Subject: Unbelievable difference
Charlie, I received the GRTIII trigger today and it
was as easy to install as all of your website info
said it would be. I have a brand new Gamo Whisper
.22 cal with a Gas Ram powerplant and synthetic camo
stock and I shot about 50 pellets thru it before
your trigger arrived. It is a very accurate and
powerful rifle (840 fps with 15.88 gram pellets) but
after installing your trigger...all I can say is
WOW!!! The GRTIII is everything and more that I have
read about on the many forums and blogs. The pull
weight, smoothness and true 1st/2nd stage feedback
are exactly what I expected. I saved the stock
trigger and spring etc, but I'm fairly sure that the
stamped, sheet metal trigger and parts will not be
re-intalled in this gun during my lifetime!
Let me also thank you for the quick delivery, 3 days
from your place to mine here in Idaho. And...even
more importantly, the install was as simple and
straightforward as your instructions. One note for
late model Gamo Whisper CSI owners... the "E" clip
is on the reverse side of the trigger assembly, and
there is only one clip due to the trigger
hinge pin having a shoulder on the near side that
retains it ("E" clip is on the opposite side that
Charlie shows in his picture/instructions looking
right to left with the trigger on the right, muzzle
on left and barrel on top).
I
just finished putting 50 more pellets downrange and
what a REMARKABLE DIFFERENCE your trigger makes. I
can only compare it to my HW97K with a Rekord 2
stage trigger and for this Gamo rifle it is as close
to the Rekord trigger as I could possibly hope for.
For anyone looking to get $500 performance from
their $200 gun, get Charlies GRTIII trigger for $32
and save $268!
Thanks again Charlie for the service and support you
provide to air-gunners.

Charlie,
I
ordered your GRT-III trigger for my Gamo Whisper VH
because it was recommended by the Gamo customer
service agent when I called to complain about the
Whisper’s excessive trigger pull.
I
must say that I was skeptical to say the least about
the reported ease of installation. Having owned my
Whisper for only a week and not being completely
familiar with its construction I was anticipating a
challenging installation. I was wrong. I used your
GRT III Trigger Installation pictorial instruction
guide and was shocked at how straight forward and
simple the entire process was from start to finish.
In fact it took no more than ten minutes.
I
also couldn’t believe the difference in trigger
pull. The GRT III trigger made a remarkable and
significant difference in trigger pull. The lighter
trigger pull was exactly what I was looking for and
has transformed my Whisper into my air rifle of
choice.

Bob,
I've read all the
testimonials.....and I'm sure you get tired of
reading them. I don't know what else to add, you are
a genius! My wife bought me a Gamo Silent Cat for
Christmas, after listening to me complain about
range fees and ammo costs. She knew nothing about
air guns, and bought it at the suggestion of a Bass
Pro Shop clerk. I was nearly ready to resign it
closet duty, not wanting to hurt her feelings, until
I ran across your site when researching these "springers".
I've tinkered with
guns since I was a kid (just another good ol' boy
from South Mississippi) and have NEVER seen anything
make this much difference in a gun of any kind. And
this wasn't the first trigger I've swapped either!
Your trigger is what these guns need to turn them
from junk into gold.
Thanks again for
offering a quality part at a reasonable price, and
getting it here so quickly. I only wish you were
still tuning!
I hope you and
your family have a wonderful New Year.

Your GRT III trigger
was shipped to me promptly. Taking it out of the
package, I immediately noticed that the workmanship
was outstanding. Installation took me only about 10
minutes, but while the gun (Gamo Silent Cat) was out
of the stock, I took some extra time to look at
everything and admire the workmanship. The install
was a snap and I feel like I could have done it
without instructions, it's that easy. After putting
the gun back together, the first shot came as a
surprise since the yard long creep was gone. I was
convinced that the standard Charliedatuna
adjustments could be improve upon so I took my allen
wrench and screw driver and got busy. Long story
short, I returned the adjustments to just about
where you had them set up, so I guess you really DO
know what you're doing. Great trigger makes a great
improvement to my Gamo. Thanks.

Hi
Bob,
Derek
MacLean here, you may remember that I wrote to you
via your CharlieDaTuna web site some time ago
commenting on various aspects of the articles
therein.
Following
requests made to me here in this part of the
World to sort out the triggers on some Gamo CFX
models I got my son Clive MacLean, who lives in
Wayne, Illinois to order three units from you. As
my younger son was visiting with his brother he was
able to bring them back to South Africa
on his return home. This certainly saved a bit on
the postage etc. and ensured their safe passage
avoiding the highly possible theft enroute through
our postal system. I understand that you are aware
of this problem having experienced it with other
orders from Africa.
I
think that I previously explained that, apart from
smithing air guns here I also coach air rifle
shooting at a local college. This morning before
attending a coaching session in the afternoon I took
the opportunity to fit one of your triggers to a CFX
used by one of my top Springer shooters. This young
man shoots very well with his CFX but has never been
happy with that dreadful Gamo trigger let-off. I
have to tell you that both the young shooter and
myself were absolutely amazed at the result. Our
complements to you Sir - a first class design and
great engineering quality.
There
is no doubt that when word gets around to the many
shooters here who use Gamo rifles I will have to get
my son to order me further supplies.
I
have recently written and published through the
college a 'how to' booklet on the techniques of
target shooting both the Springer and Sporter (PCP)
rifles in the three positions. This has been quite
well received by the school shooters here. As I
note your postal address in the GRT-111 installation
instructions I am taking the liberty of sending you
a copy that I hope may be of interest to you. Your
comments would be appreciated.

Hello Bob
Here's some feedback on my recently purchased
trigger.
I received the trigger in just 5 days from ordering.
It took me about 10 minutes to fit to my Gamo
shadow.
I didn't need to adjust the trigger, it feels
perfect.
It has transformed the gun completely, the old
trigger had a really long first stage and was very
heavy when firing. Now it is
a lot lighter and very precise. Anyone in doubt
about buying and fitting one of your triggers should
just
go and do it. It is worth every cent.
Thanks for brilliant product.

My first shot out of it hardly got on paper,

Dear Sir; I thought I would comment on Your GRT III

let Me say Your instructions for installation are

It’s a snap 15 minute start to finish job. It made
My Gamo air rifle a different gun. The trigger
travel distance was cut in way less than 1/2. And
the trigger pull weight was cut by 75% at least.
The GRT III trigger is all you said it would be
right out of the Package.

trigger in my Gamo Whisper (.22cal.). I preformed
the installation in about 5-10 minutes and had no

The GRT-III has
brought this rifle from the "sorry I ever bought

much better than a lot of my standard trigger

Hey Bob,
When I got my Gamo
Viper, I didn't even shoot it before I installed the
trigger. The trigger was a breeze to install, being
mechanically inclined; it took less than 5 minutes.
(2 minutes for installation, 3 for admiration of
this masterpiece) Overall it is beautiful trigger
on a beautiful gun, what more could you ask for. How
about an amazing SHOOTING gun?
I am so used to
shooting around 3-6 lbs of trigger pull that when
this thing fired I just laughed. My trigger was the
smoothest action, and right when you hit that spot,
it fires, precisely the same spot every-time. The
pull is so light it’s almost effortless. In 2 hours
I had already put 500 shots through the rifle. I
loved it so much but unfortunately I ran out of
ammo.
Not only does the
trigger add a special high class look to the rifle,
it adds superior shooting economics, unmatched to
any rifle I have ever shot.
I swapped out my
target every 10 shots (50 Targets) the first few I
used for sighting my rifle, I did this at 20 yards.
By the 32nd target, the gun seemed to be broken in
pretty well, and I was shooting shot clusters of 10
in the size of a DIME! (Obviously its 70% operator,
30% gear) But yes, it is the most accurate
combination with the 3-9 X 40 Glass Etched BSA
Riflescope, and your trigger. I mean dead bulls
eyes.
I love your trigger

P.S., I was at Kittery
Trading Post in Kittery Maine the day before my

he had made my day since I had already purchased one

grt III trigger
Bob,
the GRT lll trigger in my Gamo whisper is a great
upgrade. Your shipping was very quick {3 days}.
Installing per your directions was very simple. best
part this has turned my rifle into a much better
rifle. the trigger that came in the rifle was very
lacking. The pull must have been three inches and at
about nine pounds. new trigger is just right.
Believe it is even smoother than the Volquartsen in
my Ruger 10/22. it has made my Gamo much more
accurate and fun to shoot. have noticed that the
rifle is much more selective on pellets than I
expected. have shot several different ones and it
likes Beeman all purpose ones best. anyway you have
a great product, great shipping, and made my rifle
much better than new. Will likely have a tune up by

all day here, but I wanted to try a few shots from
my porch just for the hell of it. I can't believe
that this is the same gun. The trigger pull with the
factory trigger was slow, heavy, and creepy and
pretty much a crap shoot as to when it might
release.
My first shot with the GRT III was a clean, crisp
release, maybe 3lbs at most.
All I can say is UNBELIEVABLE!
This is like the difference between a cheap double
action revolver and a match grade rifle. I can't
even feel the smallest creep, it's absolutely
amazing. Thank you for making such a fantastic
product.

Hello Charlie,
I
just finished installing my trigger and here are my
thoughts andcomments:
"I want start off by saying I have NO prior
gunsmithing experience. With that said, installing
the GRT-III was extremely easy and fast. I cannot
emphasize how easy it was. I was very nervous about
installing a trigger because I have never even taken
apart an air rifle, much less install after market
parts. It took me under 5 minutes to take apart my
rifle and install it. As for the trigger, $32 is a
steal for what you are getting. It has made my
Benjamin Super Streak a pleasure to shoot. Hats off
to you Charlie for making a quality, high class
trigger that really compliments my air rifle."
Thanks again Charlie for the great trigger. I only
wish I could install this trigger on any air rifle.
:)

Bob/Charlie, I bought two of your GRT-III triggers
about two years ago for my matching pair of Gamo CFX
.177 and .22 air rifles, and I wanted to say those
triggers are STILL fantastic. I have poured
thousands of pellets down those rifles, and I can't
help but smile each time I gently squeeze that
beautiful gold trigger. These two rifles easily
produce sub .25" five shot groups @ 25 yards, and
the triggers make it considerably easier than the
stock Gamo triggers. The durability is all anyone
could hope for, and I am about to get my .22 CFX
back with the Air Venturi gas ram installed, since
the mainspring snapped. This should get very
interesting. Oh, if you can, would you put this up
on your Testimonials for the GRT-III page on your

I used to think
that the trigger pull on my

the absolute worst trigger from the factory

I bought my Gamo Big Cat air rifle and

horrible trigger was. Likewise, I thought that the
aftermarket trigger that I put in my 10/22 was the
best upgrade that I had ever made
on a gun

the GRT-III trigger in my Gamo.
Without

THE GRT-III

Just wanted to drop you a line to let you know that
I received the GRT III I purchased from (and quick
too, only 2 or 3 days) and I just got thru
installing the trigger (finally had time) and the
first shot was AMAZING. The first words out of my
mouth were "HOLY MOLY!" It has only taken one shot
to realize that this is a totally different gun than
I bought. I was shocked and thrilled. Very, very
smooth! I am not a very good shot with any type of
gun (bowhunter only), but with this trigger and my
Gamo CFX Combo. the squirrels and varmits around my

Not being a clock watcher I forgot to record the
time it took me to install my new trigger in my CFX,
but it didn't take me as long as it took to make a
cup of coffee in the microwave . I will be ordering
one for my wife as a jewel for her charm bracelet.
The trigger pull went from 64 oz. to 24 oz. in one
move, the take up is just how I would set it, the
offhand groups went down by a huge margin. If any
one has any doubts, put them aside and get one of
these triggers ASAP, and start realizing your
potential and that of your equipment when you have
installed one. Here on the East coast we do not put
up with any BS and this trigger marches to that

Hi Bob
Thanks for your prompt shipment, the trigger was
almost too easy of an install, just took a couple of
minutes and it was in. Couldn't wait to try it, even
with out my new scope installed I just had to go
outside and try it out, I have one word to describe
it SMOOOOOTH, lol. I felt the difference right away,
It really changed the way the rifle shot completely,
No more waiting, what seems like an eternity for the
gun to fire, and the trigger pull was perfect, I
didn't change a thing. Can honestly say it was a
valuable upgrade to my gamo big cat 1200. Gamo
factory triggers do not do an air rifle justice at
all. not very adjustable to me. But the GRT-III is
really sweet. Not downgrading it at all, but I have
one comment to add, I wish the one you make for the
gamo was a bit longer, but thats just me I have
rather large fingers, anyway thanks so much, GW.

Bob,
I
got the triggers last Friday. They were easy to
install and it only took about 40 minutes for both
rifles (CFX and Super Streak). The triggers did
wonders for the two rifles. Before installing the
triggers it was very tough to get respectable groups
with the Super Streak and boy did I keep a sore
trigger finger. The CFX was just ok. But I knew I
could squeeze more accuracy out of it with a few
mods. So after doing some research and reading the
great reviews and results that others had gotten
with their GRT Triggers, I had to give it a try.
Now, my rifles seems like they had major work, but
just adding the trigger makes them feel and perform
like different guns. They are more enjoyable to
shoot and I have the confidence that I will hit my
target.
Wow! What an idea and product, finally I got a real
difference maker that is well worth the money. I
would highly recommend. Big Thanks,

GRT trigger
Bob,
I received your GRT-III trigger this afternoon and
installed it in a Remington Summit .177 cal air
rifle.
Just like everyone else I feel that there is only
one word to describe the transformation, that word
is WOW! I bought this air rifle and was very
disappointed, not in the rifle overall but
specifically in the trigger feel and action. As a
matter of fact I was about to offer this rifle to my
friends, give it away to anyone who wanted it. I was
that disgusted. Now I think I'll keep it.
I shot forty five pellets this afternoon fine tuning
the zero on the scope at 30 yards and was able to
put three almost on top of one another, my worst
group was a little larger than the size of a half
dollar and this was when the wind picked up.
The trigger installed easily and as per the
instructions on your website. There were no
surprises.
You've done a great thing for people that are going
to shoot these rifles.

Hi
Bob,
Just recieved the trigger this afternoon and
had already read through the pfd files I downloaded
from your site. I have done trigger jobs on Ruger
10/22's, Remington shot guns and a Colt AR15, all of
which were not too bad. Now when it comes to
putting in your trigger in my Whisper, I've never
seen such an easy job. It was the quickest and
simple, straight forward installation. The only
thing I had to do was take the rifle down again
because of a small plastic roller that goes into a
guide in the stock, it fell off the peg and I missed
that putting it all together. Now to the meat of
the issue is the trigger worth it.
I
couldn't believe the feel and let go of this
trigger. Surprised me on the first pull. What a
great job you did on this trigger. It is worth
every penny and if anyone buys an air rifle they
should do your trigger job before they sight in the
rifle. I have owned this rifle only one month and
didn't like the creepy trigger in it right from the
start. I talked to a gun smith a Ace Hardware in
Lacrosse Wis and he turned me on to your web site.
He said the trigger is well worth it he did your
trigger job for a customer. When he fired it is was
really impressed with it. I took his advise and
glad I did. I will be showing this rifle to other
air gunners in the area. I wish I had 2 Whispers to
show the before and after but this rifle will now
speak for itself. Now the brag sheet. I have been
shooting all my life and was a high firer of the
battalion 98 out of 100 for score with the M16 A1.
Now with this trigger job I will be able to improve
on that one.
Thanks Bob for the job you did in the design of this
trigger. It is well worth it and now I enjoy this
rifle. Keep up the good work.

Byproduct of your GRT-III trigger
Dear Charlie:
While I have
previously written to you to express my gratitude
for your having created such a fine product in the
GRT-III, I’d also like to pass on to you a little
byproduct of what it is your trigger has done for my
oldest son.
As a little bit of
a background, my son suffers from a mild learning
disorder. He is in a classroom setting where he
receives extra attention in the subjects which most
frequently cause him trouble, ie., math and
reading. Partially, as a result of this extra
attention, he exhibits signs of low self-esteem.
While I go out of my way to tell him how great a job
he is doing in school, it’s obvious to me this extra
attention causes him some anxiety.
My reason for
getting into air guns was a result of my trying to
find something both boys and I could do as a
family. Both of them love to shoot rimfire and
centerfire and the oldest is actually a pretty fair
shot with a revolver/semi-auto and a rifle.
Unfortunately, not knowing anything about air guns
prior to buying a Gamo Viper and 220, I just
happened to pick the brand of rifle with the worst
triggers available.
Prior to
purchasing your trigger, I told the boys they simply
needed to practice with their rifles in order to
keep getting better. While some of the groups the
boys would shoot were actually quite good, the
occasional flyer would often spoil the results. It
was obvious to me their trigger fingers were getting
sore from pulling so hard on the stock Gamo trigger;
hence, this led to the occasional flyer.
My oldest was
actually becoming quite discouraged, and I found him
sinking back into the mood of “I’m just not good
enough.” Then…I purchased your trigger.
On our first
outing together, my oldest son’s eyes actually “lit
up” when he saw the group he produced with the
GRT-III trigger. He simply couldn’t believe how
well he was shooting and how tight he could hold his
groups. He was happier then I’d seen him in quite
some time and all traces of the “I’m not good
enough,” feeling was gone. I swear he must have
come up and shown me one target at least 5 times, he
was so proud of it. Of course, so was I.
He just recently
graduated from the 15 yard course I’d set up in the
woods behind my home, to the 30 yard course. At 15
yards, after installing your trigger, he could keep
6 shots within a span I could cover with the
fingernail on my little finger. At 30 yards, he can
already keep 6 shots within a one inch circle I draw
on a piece of paper as an aiming point. My next
step is to put him on the 50 yard course and see how
well he does.
Charlie, the
transformation in him is just astounding. His whole
attitude about joining his little brother and I as
we head out to shoot has totally changed. He’s now
eager to finish his homework when he gets home from
school so we can go back to “our” range.
I realize that as
a tuner and businessman, you’re interested in making
money and building a happy clientele. Sometimes
though, you actually DO touch people in ways you
might not fully expect. You certainly did in this
case, and I couldn’t be happier about it.
Sincerely,
Bob Petty

Thank you. I have built and repaired things from

This was the easiest and most straight forward
replacemnt I have ever done. Everything on your end
worked as shown and from my end I didn't even lose
the "jesus clip."
I bought the CFX last fall. It was supposed to be
accurate anmd was relatively inexpensive and Pyramid
air had a garage sale so I picked up and open box
even cheaper than the retsil price by 50 bucks. I
figured if I didn't enjoy it I could get a
goodportion of my investment back.
I had believed the stories about the Gamo trigger
breaking in. It didn't. After approximately 3000
shots it still stuck on occasion and never quite
released the same for more than 3 or 4 shots in a
row.
I ordered your trigger last Thursday and it arrived
today. I spent more time opening the envelope and
rereading the instructions than I did diassembling
and reassembling the gun.
20 shots in a hole smaller than a quarter. It is
only 45 feet but it was a huge improvement for me

I have a Gamo Whisper, which I

new quality air rifle was going to run ~$200-300 and
then I came upon the GRT-III recommendation and
thought I'd give it a try. I received the trigger
and installed it within 15 minutes. I am not
mechanically inclined and was sure I'd screw up the
installation but it was very straight forward with
the downloaded instructions. I couldn't believe the
change it made...1/2-1 inch groupings @ 30 yds ( I
was lucky to get 6 inch groupings with the factory
trigger). This morning I tried it out on the gophers
in our field...two out of the first three shots
found their mark (the third was a 60 yd shot). To
anyone with a Gamo, you MUST buy the GRT-III
trigger, it will transform your piece of crap into a
very accurate air rifle.

Hi Bob
I wanted to drop a few lines about your GRT-lll
Trigger. This trigger is Absolutely Fantastic. You
are a Genius and a God Send too all of us. With your
Trigger youhave transformed my Crosman Sierra Pro
from an air rifle I would occasionally shoot,
too one I find hard to stop shooting. It is now on
my list of favorites. Your trigger is so easy to
install with your instructions, it’s incredible.
Since
installing the GRT-lll trigger these are some of the
changes in the performance of the Sierra Pro:
1.
The trigger pull went from 88oz.(5.5lbs.) too
24oz.(1.5lbs.)
2.
The trigger has gone from a rough travel with a
heavy break too a smooth travel with a very crisp
light but manageable break.
3. It has shrunk my groups @ 33 feet from 1 inch too
3/16 of an inch
4. Not to mention it also adds to the aesthetic
looks of the gun. And all for a very fair price.
I Can't Thank You Enough. I am finally getting what
I expected from theSierra Pro.

RE:
Incredible
Bob,
Got the trigger in today's mail. I recently
purchased a Crosman Quest 1000 and the reason that I
purchased the trigger was because the factory
trigger required a tremendous amount of trigger pull
to shoot. Adjustment of the supposedly 2 stage
trigger did nothing other than shorten the second
stage while increasing the free play of the first
stage. I am used to shooting big bore and varmint
rifles that have a 1 to 2 lb trigger pull and was
looking to improve the feel of the Quest 1000 to
that of what I was used to.
So I was a little apprehensive that your product
would perform as advertised.
The installation went smoothly and as the
instructions indicated it took about 15 minutes to
do the install.
I did not do any modifications to the first or
second stages and the trigger housing was real clean
without any sharp edges so there was not any
modifications that was required in that respect.
The safety engaged without any problem and the
trigger pull was noticeably lighter which is what I
was hoping to achieve.
After assembly I test fired a few shots at my target
in the back yard and the difference was incredible.
The trigger pull was smooth and consistent from shot
to shot. It has made this air rifle a real pleasure
to shoot.
I am duly impressed with this trigger and am glad
that I made the decision to buy it and I will
definitely recommend it to my friends that have air
rifles that can accommodate this trigger.
Thank you for a very superior product.

Trigger comments
Hi Bob
A word of thanks for the prompt service I received.
From activation of my PayPal account to notification
of payment received and order confirmation, took
only 2½ hours.
I received the GRT-III
in my post box a bit more than a week ago. It took
10 days from placement of order to my post box. Not
bad for standard mail from the US to South Africa.
Installation in my son's GAMO Shadow 1000 was
straight forward with the help of the supplied
instructions, and the whole process including
lubrication took no more than 20 minutes.
I tested the rifle at 10 meters (33 ft) and WHAT
A DIFFERENCE. The first shot went off before I
realized that I had pulled through the second stage.
When using the standard trigger, I would sometimes
run out of breath before the shot went off, due to
the heavy pull and long creep. A few test shots
later I got the feel of the trigger and proceeded to
shoot some groupings.
A five shot grouping of 7mm (0.27 inch) using H&N
Barracuda Extra Heavy .177 was easily attained. I
would struggle to get anything close to this with
the standard trigger and unpredictable pull.
The GRT-III trigger has transformed the rifle from a
"Why the hell did I buy this", to a
"Hey this ain't half bad at all".
I highly recommend this Trigger to anyone
who has ever had the misfortune of having to use a
standard GAMO Trigger.
Thank you for a GREAT product and an
excellent
WEB Site.

Hi Bob,
I
just returned a short while ago from giving the new
GRT-III a test drive. ... I installed it on a Crosman Phantom,
- what a difference!!!
Absolutely great, - no comparison with the factory
trigger. This trigger is very easily installed, is
"quick" and has an "easy touch" to it. I also have a
Gamo Whisper, which I'll be ordering a GRT-III for
this coming week. Also can't say enough about the
quick turn-around and service after the order. I
would highly recommend anyone who's "thinking about
it" - to go ahead and buy one.
Thanks,

which includes taking apart the airgun, replace the
trigger blade, blue Loc-Tite the stock screws and
put back together the air rifle took less than 15

Changed the 5 air rifles from mediocre to excellent

Received the GRT III trigger for my Gamo 1200 rifle
yesterday and after a easy installation, I was able
to shoot 1/2 inch groups at 30 feet. What an amazing
improvement in the trigger pull. No more endless
drag and hard catchy pull. Thanks to the GRT III the

Subject: Freshly
tuned Whisper
I recently had my new Whisper Deluxe tuned by Bob
(Charlie Da Tuna). I can't begin to tell you how
happy I am with the whole experience, just great
service all the way around.
I've had it back for a few weeks, the first thing
that I did was mount a new Leapers 3-9X44 scope on
it with a 1 piece Accushot mount. I had issues with
the scope creeping with the factory set up, so far
the new gear is working perfectly. I already
installed the GRT-III trigger, that went in after
the very first time that I shot the gun. I also
stuffed some foam down in the stock, I think that's
helping dampen things down a bit.
So far I've only managed to squeeze about 100
rounds through it due to the cold weather here and I
know that it's going to take quite a few more before
it's really broke in but man I just can't believe
how nice it's shooting already. Now keep in mind
that this is my first springer or air rifle aside
from my little Daisy when I was a kid, so I don't
have anything to really gauge it by. I do know the
recoil seems to be about 1/3 of what it used to be
and it's much quieter and just all around smoother.
There was a little hitch in the cocking mechanism
before the tune and now that's like butter. As for
the noise, it's makes less noise than the little
Crossman C11 CO2 pistol I have.
I can't thank you enough Bob, you were a pleasure to
deal with.

Bob,
The GRT-III arrived today, thank you for a quality

I
tend to tell things like I see them, no BS here

nearly overwhelmed in this small dealing with you.
The GRT-III is indeed the unit I saw installed in a
Gamo David Slade had last year (I wasn't sure before
receiving ours) but even after seeing I had ordered
the correct unit my skill certainly do not match
"The Trigger Man's" however after looking at the
most comprehensive detailed documented instructions
I have ever seen for anything I felt I would attempt
installation myself (David had offered to help if
needed) and a most satisfying few minutes of work it
was.
After just a few test shots I went ahead and
adjusted both the first and second stage (it did
arrive set well for most peoples use, just good to
go, but this is going to be a back-up/loaner FT
rifle and I wanted to see what it would do and I
feel it will be most adequate for my intended
purpose.
You sell a fine product and set a standard for
instructions so high no one I have dealt with even
comes close. Also your prompt communications and
shipping are A+. I will be posting a small review on
airgun advice and will highly recommend doing

Hi Bob
Just wanted to tell you to add me to your long list
of satisfied customers. I recently bought a
Gamo Varmint
hunter and although I loved the gun I hated the
trigger from the start. I started doing some
internet
research and soon came up with the GRT-III trigger ,after
reading all the testimonials
I decided to try it and im
glad I did. It was very easy to install with the
great instructions you provide , and it makes all
the difference in the world in your shooting. I went
from three inch groups at 25 yards to same hole
groups. I have no use for a gun that I can't shoot
accurately and your trigger transformed my gun. If
you own a Gamo rifle you owe it to yourself to spend
another $32 and get this trigger you wont be
disappointed , isn't that why
you bought your gun to start with , to be able to
shoot well ?
Thanks

Es una pena que este gatillo no sea tan conocido en

para que más gente pueda disfrutar de esta mejora
para las carabinas Gamo. Después de todo, se fabrica
en mi país y es nuestro amigo americano Charlie el
que se encargado de mejorarla.
Yo no soy un experto en carabinas y no hablaré de
tecnicismos, presión del gatillo o fases, pero sí
que puedo decir que mejora considerablemente la
precisión a la hora de disparar. Las palabras de mi
mujer la primera vez que lo probó lo resumen todo:
¿ya está? Y es que es tan suave que casi no hace
falta hacer presión. La sensación de calidad es
evidente. Por lo que vale, es altamente recomendable.
Lo que puede echar para atrás es su instalación,
chupado. Me llevó menos de 3 minutos montarlo y es
realmente complicado hacerlo mal siguiendo las
instrucciones disponibles en la web. Pero como es
mejor verlo que contarlo, aquí tenéis un video

in Spain, that's why I write my impressions in

I'm not an expert in airguns and I won't use
technical words, pressure of the trigger or steps,
but what I can say is that it really improves the
precision when you shoot. My wife's words summaries
everything the first time she used it: done already?
It's so smooth than you almost don't have to press.
The quality feeling is clear. For its price, it's a
must.
What can make you hesitate is its installation,
piece of cake. It took me less than 3 minutes to
install and it's really hard to do it wrong if you
follow the instructions of the website. But is
better to watch than to tell it, so here you have a

GRT Trigger
Hi Bob,
I received the trigger and fitted it that evening to
my Gamo Whisper, it was a breeze! Your installation
instructions are well detailed and very easy to
follow. The overall finish of the trigger is
excellent, no burrs or other imperfections and the
tooling is all perfectly finished. Small details
that so many manufacturers seem to overlook these
days.
I have now had some time to test the trigger and boy
am I glad I bought it. There is no comparison
between your product and the stock item. At first I
was taken by surprise at the weight of the action,
first shot I had pulled the trigger before I
realized it. After a few shots something was
happening that I had not experienced with that gun
before using the stock trigger. I found myself in
the in the happy knowledge of knowing when the gun
was actually going to fire! Fairly useful that. I am
able to consistently hit a 3/8" target at 30 yds
without having to take 2 breaths per shot. The gun
is a real pleasure to use now thanks to your fine
product.
Cheers,

Testimonial for your website
My wife ordered the GRT III for me for my Whisper
.22 and not only was Charlie's turnaround quick and
painless but the product is great too. I installed
it today in about 15 minutes. I don't know much
about gun internals but the excellent directions and
pictorial helped quite nicely.
So what is the difference for me? I would loose my
breath trying to pull the stock trigger consistently
and have to re hold all the time. I think that Gamo
must err on the side of stupidity. What I mean by
that is that the trigger is so hard to pull through
the "2nd stage" that they must have made it that way
on purpose so that those "special" people that don't
practice proper safe shooting techniques and walk
around with their finger on the trigger of a loaded
gun don't shoot by accident. Now the trigger is
very light but you can feel the 2nd stage. 2nd
stage is quite short and quick and I think that this
is perfect as the it requires almost no effort to
pull though but you do feel it. I can't wait to see
how my groups will improve now as I know the heavy
2nd stage was so heavy that I had difficulty not
shifting the sight picture when I finally pulled
hard enough to get through the factory 2nd stage.
Thanks for a great product and service. The only
improvement I can think of is to offer it in other
finishes (nickle, pewter, black anodized, etc) in
addition to the standard gold.

GRT-III Trigger - WOW!!!
I'm
so impressed with Bob's aka Charlie's GRT-III
Trigger, I thought I'd share my letter to him:
Dear Bob,
I ordered your GRT-III trigger on Sunday and
received it today, Wednesday. Thanks for the fast
shipping. I had it installed in my old .177 caliber
Gamo Hunter 220 (made in Spain) in less than 15
minutes using your excellent written and picture
instructions. First thing I noticed was your
incredible workmanship. Your pin tolerances were
absolutely perfect in my rifle. Next, I quickly got
out in the back yard and set up my old Marksman
pellet trap and "homemade" targets.
You were exactly right - WOW! What a difference your
GRT-III trigger makes. It took me a few shots to get
used to the new lighter, crisper feel. But, soon I
was shooting better groups than ever before. I had
always had trouble shooting good groups with the
stock trigger. Now even my "plinking" pellets are
grouping better. As you mentioned, the GRT-III
trigger doesn't necessarily improve the accuracy of
the rifle, but it sure does improve the accuracy of
the shooter!!!
Thanks again, Bob. WOW!
Sincerely,
George Garrett

GRT-III trigger in my Gamo Whisper with gas ram
This is an email sent to Bob, "Charlie" earlier
today.
I ordered the trigger online Monday, 29 Dec 2008. It
arrived today, Wednesday, 31 Dec 2008
WOW. That had to be the easiest and most worthwhile
investment of 2008. I have a GAMO Whisper, with
modified gas ram, and I think from opening the
packing envelope to having it installed was about 30
minutes, including the time spent looking for my
torx set, and firing a “Before” 3 shot test string.
I used the pdf instructions direct off my laptop.
Attached is the scanned target from my test. The top
is three shots, offhand, with the original factory
trigger. The lower is after installation of your
GRT-III. Again three shots offhand, both fired with
Beeman Crow Magnum pellets. The “flyer” on the lower
target was the first shot and I was expecting a
jerk, or difficult pull, like with the original
trigger. That’s what you get, squeeze hard with a
silky trigger and you get down and right. All I can
say is smooth. With a little more practice and I’m
sure it will be shooting one hole groups. Not bad
for a plinking fun gun. Thanks for making it easy.
It has made a HUGE improvement. Thanks

Thank you, I received the triggers in amazing time.
I'm just impressed by that fact alone. I installed
both on my 800 & 1000 Quest Crosmans. Yes, not a
Diana,Beeman, Gamo or otherwise, just the poor man's
airgun, and what a difference it made. This single,
simple, addition made it possible to bust walnuts at
30 yards plus with the addition of good mounts and
sights. I like to hunt, so this added an exceptional
addition that was the ULTIMATE REWARD in upgrading
any of my several air guns. I would challenge anyone
out there to a civil shooting match no matter what
gun you may have. No kidding, this item just
enhanced my ability ten fold. So Much for that and
have a decent Christmas and New Year (09 remember).

Hello Charlie,
Holy smoke, I don’t know what kind of alchemy you
used to make the trigger, but man it has transformed
my gamo 220, from 1.75 inch grouper at 30 yards, to
a ½ incher at the same distance. I did not have the
money for the tune, so I bought the trigger and
added a recoil pad. It feels as if I now have a
highly tuned precision rifle in my hands. Today two
tree rodents were just under 30yards from me barking
at each other. I took the one facing me from a
standing of hand shot right behind the ear. I
reloaded, breathed settled my crosshairs lightly
squeezed the grt and the second squirrel fell the
victim of a head shot also. The only reason for any
of you perspective buyers not making this purchase
might be your reluctance in becoming a mass murderer
of critters. This is the best bang for the buck by
far.
Thank you grand wizard of airgun triggers!

GRT trigger
Bob,
I wanted to let you know about my experience with
your trigger. I was a little skeptical that the
installation would be simple from the level of
detail in your instructions. I installed the
trigger on a Gamo Shadow Sport. It was probably the
easiest fix/upgrade I've ever done on any
firearm/pellet gun. It dropped right in, no
fitting, filing, polishing, adjusting necessary.
The improvement to the pellet gun is unbelievable.
This one simple inexpensive upgrade will increase
the enjoyment I get out of the this gun 10 fold! I
have never felt a trigger like this on an air rifle.
Thank you!

Dear Bob (aka Charlie)
Can't say enough about this trigger. I
ordered it Friday, received it on Monday at 2:30pm, and was shooting dime size groups from 30 yds by
2:45pm. Those of you with Gamo's (Whisper, Varmint)
look out for that roller pin when you remove the
receiver- it tends to have a mind of its own.
Luckily, as Bob mentioned in the installation, I was
expecting it to fall out. I can't get over how light
the trigger pull is.... my first shot went off well
before I was expecting it to. The first stage was
like butter- very short travel until you feel that
slight stop before second stage. Once you hit the
2nd stage, all you have to do is breath on it to
discharge. Those of you with Gamo's or any other
compatible rifle should SERIOUSLY consider this
upgrade... I never realized how bad the factory
trigger is until I installed it. I've got a Beeman
R7, and the feel of Bob's trigger in my whisper
blows it away.
Thanks again,

Hi Charlie,
I
had bought a Cabela’s Sportsman and the trigger on
it was even usable! I’ve had a lot of air guns but
I haven’t bought any new ones in a long while. If
this is the way all the new triggers are I wonder
how people even hit a target from 25 yards out!
After the first shot out of the gun I was ready to
take it back. Instead I tried the trigger
adjustments that they had installed on the gun. This
made no difference or maybe even made it worse. Took
the gun apart only after about 10 shots and looked
at the trigger mechanism and was not happy with the
looks of the prefab, cheap looking mechanics of the
anything inside there! The gun looks great and you
would never expect something so cheap looking inside
it! It is like buying a Corvette with a cheap
undersized metal pressed steering wheel rapped in
rubber. After thinking about modifying the trigger
and going thru a lot of headaches, I looked on the
internet thinking someone had to figure out this
problem already. First sight I come to is Charlie
the Tuna! Funny I have a good friend we call the
same. Charlie says he has it all figured out. Well I
got the trigger less than a week after I ordered it
and installed it as soon as I got home! It took me
a whole 10 minutes! “It was a new gun”! The
instructions where very easy to follow and the
trigger falls right into place like it belongs
there! Nice work Charlie! It is great to see that
there is still some real craftsmen out there! Great
Job and Great product! Thanks for saving me the from
the headaches of working on the trigger myself or
even taking the gun back!

GRT-III
Triggers Arrived
Dear Bob,
I ordered your
GRT-III last Sunday night and it came in the mail
Thursday. Thanks for the speedy service! The new
trigger is for a 177 cal. Gamo Hunter 890S. The
rifle has about 3500 shots thru it. It was a very
hard gun to shoot consistently. I was sorry I bought
this gun. It seemed like every time I picked it up,
I had to sight it in. I used to have a 30 year old
Beeman C1. Only had to sight it in when I changed
pellet styles. I was always wondering what was I
doing wrong with the Gamo gun. I have read all about
how to hold an air rifle, breathing techniques,
pellets, changes in temperature, etc. I never had
any trouble with the Beeman, I just pointed and shot
and rarely missed. By mistake I left the
Beeman cocked for several weeks. Thinking that I had
ruined the spring, I gave it to a friend and bought
the Gamo hunter 890S.
Well, like everybody else seems to say; WOW! Your trigger
conversion is great! Installation was easy. Took my
time. Since the stock was off, I oiled the trigger
assembly like you suggested as well as the barrel
pivot points, spring and any other linkage. Then I
installed the new trigger and put the stock back
on. Total time spent, twenty-five minutes.
The gun is totally different. Now I get nickel size groups at 30
yards, every time! I can't believe it. For two years
I was sorry I gave my Beeman away. Not anymore! My
Gamo Hunter is shooting great! After I sighted it in
with your trigger installed, I shot five English
Sparrows and one Blue Jay, all perched on a power
line, with six shots at about 30 yards. Before the
trigger UPGRADE, I always felt lucky when I
hit a bird, squirrel or bullseye. Now I shoot with
confidence! DEADLY AGAIN!

Hi Bob
I received all four of my triggers today. I was
really surprised that they came so quickly. Thanks
for the great service. It took me a half hour to
install all four, so that part was easy. Then I took
them all outside to shoot a couple of rounds. Bob I
don't know what to say. You must be some genius. I'm
sure you need to receive some award for these
triggers. All four my rifles have been transformed
from OK to phenomenal. I didn't even adjust them.
They work perfectly the way you set them up. I could
not believe that some small metal component that
arrives in a brown envelope can make such a huge
difference. Bob, what also impressed me was the
quality of the triggers and the tolerances.
Everything fitted together perfectly, without being
too tight or too loose. They also look great in the
rifles. I saw some guys asking for a different
colour, but the gold really works for me. Thanks for
the great product and great service. I don't know
what more to say. I was a little frustrated with my
Gamo's. I really like them and have learned to live
with the triggers. Now they are perfect. I also have
two Diana's a Hatsan 1250 and an AR1000. As far as
trigger feel goes now, the Gamo's are way ahead, and
that's saying a lot considering I'm used to Diana
triggers.

GRT-III
Hey Bob,
Received your GRTIII trigger the other day for my
Gamo Varmit Hunter. I saw other post that said even
a cave man could do it...so I figured here goes! My
first surprise was when the trigger housing popped
out and things went flying! After multiple swear
words and promises to God if only He's get me
through this, I got the trigger in. I did go back
and forth thru the pictures on my computer a few
times because I had all these left over pieces and I
thought that I really screwed up.
Your GRT trigger is so great in its simplicity!
After I had it back together and test fired it, I
actually thought I was shooting someone else’s gun!
The trigger pull was so smooth that at this point I
don't even want to mess with it. A nice crisp break!
I
just picked up the old trigger and looked at it and
thought "what a cheap piece of crap!" Yours is a
quality item and it even makes my Gamo look good!
Anyone out there reading this??? (I know its at the
bottom of a thousand other testimonials)...This is
the best investment (at an unheard of price) you
can make for your air rifle.
Thanks again,

Comments from Russia on GRT-III installation
Good day
I
received GRT trigger 3 weeks ago (huge thanks!) and
now I guess it’s time to sum up the results.
First, some words about the rifle.
Mine is Gamo CFX Royal, produced late 2007, upgraded
with Russian-made gas spring. Gas spring force is
set to 59 kg (tuned for optimal performance with
Crosman Premier Ultra Magnum 10,5 grain pellet,
which I prefer most for quality/accuracy/price
reasons). Other upgrades include custom-made piston
seal with zero “dead volume”.
Spring and seal are both made by “Petrucha”
–
well-known Russian custom airgun and parts maker
(and researcher, he’s highly respected for that
part). Optics is Leapers 3-9x40 MilDot installed on
Diana Special Magnum mount.
Using all this I can achieve 8-11 mm groups of 5
pellets @ 25m with ease. Sometimes, irregularly,
groups shrink down to 6 mm, but that’s just luck I
guess. At 50m best average groups tend to grow up to
about 25mm and pellet starts to loose speed
–
so I got to aim close to 1 mil upwards. Longest
aimed shots I remember were some 75m just to test
grouping, which was about 50-60 mm. All in all, my
rifle made me proud many times.
Thing that made me wish for more was the trigger:
too long a pull (about 20+ mm), too much force to be
applied, too little info from the movement (“first
stage” was just compressing the spring). I felt that
trigger was the weak spot
–
long heavy pull made my rifle “want too much” about
holding it steady and sometimes resulted in failed
groups.
Of course, I polished all the surfaces, screwed in
all the screws and did some voodoo about the
springs, added some washers etc. but all that could
not solve the problem the way I wanted.
I
asked my friend Alexey (he is a frequent e-bay
buyer, so he knows ins and outs) to make a deal.
Then you received my letter and voila
– GRT is mine.
Installation went easy and smooth, with no trouble
at all. In fact, it's so simple that it's almost
impossible to do something wrong way.
First things noticed: trigger pull became
featherweight. Travel dropped to 11 mm and it was
real 2 stages, articulated and informative. After
installation I shot about 50 pellets in the air,
just to make iron sit back into wood. Then I
retightened screws and the real shooting began.
First of all, @25m bullets holes “jumped” some 20 mm
higher from their usual impact point. I think that’s
the first result of a lighter trigger pull
–
heavy pull makes the barrel to travel some parts of
mm downwards. A little bit of clicking with the
scope did the trick.
Groups didn’t change much
–
it was still 5 pellets in 8-11 mm groups @25m,
however there are more “doubles” and “triples” and I
even noticed some “cloverleaves”
– 4 bullets fly through almost same hole in the paper. Groups @50m were
still close to 25 mm, but with 2 or 3 holes much
closer together than the others.
What really changed is the ease of handling and
overall control of the rifle. And it feels great. My
rifle became more “forgiving” and easy to shoot. Of
course, I think it’ll take some hundred shots more
to get full understanding of rifle’s new behavior,
to tune up pull and travel to optimum and got used
to all of its new advantages.
GRT is a truly great stuff. I highly recommend it to
every "marksman" Gamo-user, however, "hunters"
should use it with care: light pull and short travel
make it not so safe in forest.
Thank you and best regards
Sergey

Hi Charlie and to say I received the trigger to day.
I have done the installation and all I can say is
SENSATIONAL and above all your trigger has the most
PROFOUND EFFECT ON GROUPING.
Your grouping comes down dramatically because now
you can concentrate on composing your shot without
having to worry about heavy trigger pull. My trigger
pull is so light now I can hardly feel it. No extra
setting was needed.
Good luck Charlie and thanks.

Hello, I'd just like to say that for the price I
feel like I just bought a new airgun for $30.00! I
like how easy it is to install, & I love how easy it
is to shoot! I didn't even need the instructions,
you just replace your trigger with this one... I
dare say "It's so easy a caveman could do it!"
I am less accurate now with this, because I'm
accustomed to SUCKY TRIGGERS. But that's my fault
not the trigger's.
My one gripe is the andonization in Gold. I try to keep a military
M40 look about my pellet gun... 1.5-6X44 Leapers
swat scope, Accushot Low profile 1 piece mount,
Gamo riser rail on a Shadow Sport. I think I'll deal
though, cuz the feeling of not fighting w/ my own
gun is amazing! I think I can take it to the range
now & work at 50 yards!
To anyone with a brain, a Gamo, & a wallet I say

G'Day Charlie,
I
have just installed your GRT III Trigger into my new Gamo CFX Air Rifle, and have to say
the difference it has made to the feel of shooting
it absolutely amazing. With the stock trigger fitted
I sometimes had to stop and take another breath in
between the shot as it was a firm pull and taking a
steady shot would take forever. Now with the GRT III trigger installed it is a much lighter, and a very,
very smooth pull. Installation was a breeze, I had
the word file and the PDF file on display while
doing the install, and it was that easy that I
really just followed the pictures from the PDF
install file.
The
GRT III is great value and anyone that has an Air
Rifle that takes this trigger and still has the
stock trigger installed, do yourself a favor and get
one of these triggers ASAP, I guarantee you will not
be disappointed, the difference is like comparing a
cheap car to a Mercedes Benz.
Thanks again Charlie, I'm going back outside to do
some more shooting!!

Hi Bob
A word of thanks for the prompt service I received.
From activation of my PayPal account to notification
of payment received and order confirmation, took
only 2½ hours.
I received the GRT-III
in my post box a bit more than a week ago. It took
10 days from placement of order to my post box. Not
bad for standard mail from the US to South Africa.
Installation in my son's GAMO Shadow 1000 was
straight forward with the help of the supplied
instructions, and the whole process including
lubrication took no more than 20 minutes.
I tested the rifle at 10 meters (33 ft) and WHAT
A DIFFERENCE. The first shot went off before I
realized that I had pulled through the second stage.
When using the standard trigger, I would sometimes
run out of breath before the shot went off, due to
the heavy pull and long creep. A few test shots
later I got the feel of the trigger and proceeded to
shoot some groupings.
A five shot grouping of 7mm (0.27 inch) using H&N
Barracuda Extra Heavy .177 was easily attained. I
would struggle to get anything close to this with
the standard trigger and unpredictable pull.
The GRT-III trigger has transformed the rifle from a
"Why the hell did I buy this", to a
"Hey this ain't half bad at all".
I highly recommend this Trigger to anyone
who has ever had the misfortune of having to use a
standard GAMO Trigger.
Thank you for a GREAT product and an
excellent

Bob,
I ordered my Gamo CFX air rifle and GRT-III trigger
at the same time. The trigger arrived, flawless,
and in a minimal amount of time. The rifle just
arrived (a week after the trigger)...my hat is off
to you for service, shipping and now support!
I was a little scared at first to disassemble the
new air rifle, but it had the Air Venturi piston
installed by the guys at Pyramid Air, so I figured
I'd give it a whirl. Plus, you sent excellent
detailed instructions with both written words and
illustrations to boot.
I put the rifle, the trigger, some tools and my
laptop on my workbench and started working. To my
surprise, it took me less than 5 minutes to remove
the receiver, install the trigger and put everything
back together again. An even greater surprise was
firing it after the new trigger was installed!
Prior to installing your masterpiece of a trigger I
zeroed in my new Centerpoint 3-9 X 50mm scope. It
took more than a few pellets due to the "when is it
going to fire" factory trigger. However, after the
trigger install, the rifle fires consistently
everytime and is much more predictable. You have
done a great job with this product and I appreciate
the added upgrade. Keep up the good work and safe
shooting.

Hey, Charlie..I really appreciate your help the last
couple days. I just thought I'd write a little
review for you to post on your website as a thank
you.
I ordered the GRT III for my Remington Summit and in
mere days the trigger was in my mailbox. I was truly
shocked at how fast I received it. After rushing it
inside, the installation couldn't have been easier
and the performance afterwards was astonishing. The
draw went from being heavy, long, and unpredictable
to having a light and clean break, which really
improved my group sizes. Unfortunately, I wore out
the safety latch on my gun, so I'll be returning the
rifle before long. I emailed Charlie to ask for his
opinion on which gun to upgrade to and that’s when I
was surprised yet another time. Unlike the run
around customer service I've grown used to these
days, I was promptly responded to, not just on one
but to all of my questions. He directed me to the
Diana 34 and because GRT III isn't compatible with
the RWS models, he offered to reimburse the expense
of the trigger. This shows that he genuinely cares
about the happiness of his customers and not just
his profit. While I won't be needing the trigger
anymore, I'll surely be back for a tune up at a
later date because of the sincerity I've witnessed.
Thanks again,

Thanks for your prompt shipment, the trigger was

with out my new scope installed I just had to go
outside and try it out, I have one word to describe

It really changed the way the rifle shot completely,
No more waiting, what seems like an eternity for the
gun to fire, and the trigger pull was perfect, I
didn't change a thing. Can honestly say it was a
valuable upgrade to my gamo big cat 1200. Gamo
factory triggers do not do an air rifle justice at
all. not very adjustable to me. But the GRT-III is
really sweet. Not downgrading it at all, but I have

gamo was a bit longer, but thats just me I have

Bob,
I
got the triggers last Friday. They were easy to
install and it only took about 40 minutes for both
rifles (CFX and Super Streak). The triggers did
wonders for the two rifles. Before installing the
triggers it was very tough to get respectable groups
with the Super Streak and boy did I keep a sore
trigger finger. The CFX was just ok. But I knew I
could squeeze more accuracy out of it with a few
mods. So after doing some research and reading the
great reviews and results that others had gotten
with their GRT Triggers, I had to give it a try.
Now, my rifles seems like they had major work, but
just adding the trigger makes them feel and perform
like different guns. They are more enjoyable to
shoot and I have the confidence that I will hit my
target.
Wow! What an idea and product, finally I got a real

Just like everyone else I feel that there is only

I shot forty five pellets this afternoon fine tuning
the zero on the scope at 30 yards and was able to
put three almost on top of one another, my worst
group was a little larger than the size of a half
dollar and this was when the wind picked up.

I installed the GRT-III in my Gamo CFX .177. I'd
purchased it about 6 weeks ago and had somewhere
around 500 shots through it. I'd read all the
reviews about how bad the CFX trigger was but
thought to myself "Eh, it really can't suck THAT
bad, i'll just deal with it." Try as i might though
i just couldn't. It was gritty feeling, it was hard
to pull, and the most annoying thing.... mine didn't
always release at the same spot.
Enter the GRT-III. I already knew i had all the
tools because i had done an earlier tear-down and
inspection of the gun. So the swap honestly took ~5
minutes. Install is dirt easy. Cock and load for my
first shot with the GRT-III , pulled nice and slow
to get a feel for it, little bit of first stage,
TINY amount of resistance for 2nd and the shots off!
Amazingly better to shoot. Haven't had much time to
go shooting but fired off a couple dozen shots out
the back door.
Bob, your trigger is AMAZING!! it completely changed

with time. The installation took all of ten minutes
or less and the improvement is remarkable. The CFX,
Hunter 440, Big cat and Storm XT are all very
predictable when the trigger is pulled and the pull
is short and sweet The accuracy is markedly improved
as is the consistency. The CFX is the most accurate
of the bunch, quarter size groups at 30 yards from a
beginner, but they all shoot much better. I no
longer have to take multiple breaths before the
rigger breaks to just get pellets down range and
hope they hit the target I just breath aim and pull
and hit the very point on the target I was aiming
for.I am having more fun now than ever before.

silver dollar size groups at 30 yards with the

it the majority of the time. (we had to aim high to
compensate for the drop) But with the GRT III we

of it. The trigger is light and crisp, allowing me
to hold on target and shrink those groups. The rifle
cocks smoothly and there is no more spring twang.
recoil is lighter and the release of the trigger no
longer affects my hold on target as it did before.
I must also praise your customer service, as it is
first cabin all the way. You kept me informed of
progress, and let me know when it shipped and the
tracking number. First class craftsmanship, first
class service, my next air rifle will be drop
shipping to you directly from the retailer. I don't
even want to see it until you've worked on it.
Best regards

Good Evening Bob,
You are the man, my Gamo 220 shoots better than most
high priced rifles I own or have shot. It's even fun
to shoot. I'm sorry it took so long to let you know
how the tune-up went but I've been away and didn't
have a chance to get any pellets through it. I've
now fired about 650+ JSB Yellow Match Diabolo's
(8.02 gr.) and the gun is much more accurate and
consistent than I could have hoped for. I've spread
the word to fellow shooters and I believe it should
result in some more business for you. I've got two
more Gamo's and once I have the funds they will get
the TurboTune as well.
Thanks again and I'll be in touch, try to get some
time to yourself this weekend....;)
Take care,
-Dan-

Hi Bob:
I wanted to let you know that after several days of
shooting my Shadow S1K that I am very impressed with
your abilities and workmanship and the service you
provide. What you have made this gun into was more
than I was expecting by far.
As I told you during our phone conversation, after
having my Silver Shadow tuned by (“xxxxxxx” edited
out) a so-called tuner that resides on the Network
54 Yellow forum, I was far from being impressed with
both the trigger mod as well as the tuning results.
It was quite a disappointment and needless to say,
he never got my S1K or any other business. I was
informed by a couple of other airgunners that I
should spend the little bit of difference in cost
and go with you but elected to go the other way. Big
mistake.
That said, and after your offer, I as you know, sent
my S1K for the TurboTune and the GRT-III trigger.
The difference in results between what you do and
what (“xxxxxx” edited out) is dramatically
different. The end results from you were what I
expected from (“xxxxxx” edited out). Live and learn
I guess.
You are a well known pro with a terrific reputation.
You will be in business for a long time and will
always have satisfied customers based on what I’ve
seen, your professionalism, abilities and the way
you conduct your business. And you are a true pro.
Thanks Bob

Hey Bob the Whisper found its way home yesterday and
I was able to do a bit of shooting. What a
difference a turbotune and the new trigger can make.
It’s like a different gun and I would never have
believed it unless I saw it for myself. It’s
everything that every body says about you and your
work and I know now why you are so well know in the
airgun field. Well worth the money and there is no
doubt that I would do it again. In fact, I will be
sending you my CFX in a couple of weeks. 
Thanks again for making this gun into a fantastic
shooter and I’ll be in touch again in a few weeks.

Mr. Werner…Charlie…Bob
I received my RWS-46 back from you and was able to
get to shoot it yesterday and today. I cannot
believe the difference in the gun. I had
reservations about spending the additional money for
your Turbotune in a fairly new gun but after reading
about you and your magic, I bit the “pellet” pellet
and decided to have it done.
I thought this gun was shooting pretty good prior to
sending it to you but after getting it back, there
is no doubt about the benefits and improvement. I
don’t know what you do or how you do it but all I
can say is that it was the best money I have ever
spent in my airguns. I’m one of those that now know
about the “Tuna’s” magic. It is just a fantastic
shooter now, much smoother, easier cocking and much
more accurate. At 40 yards I can now place nickel
and quarter size groups while before being tuned a
was happy when I got 2 inch groups. I attribute this
to the much better shooting characteristics.
I have a Gamo Shadow and a FWB-127 that will be
coming your way soon.
All I can say is thanks for the great service and
fantastic job. Keep up the good work.

Hi Robert
My B-26 arrived in great shape and your turn around
time was just as you said it would be. I expected it
might be gone for weeks. I waited to e-mail you
because I wanted to put a tin or so through it
first.
The difference that you made in this B-26 is
incredible and it’s like it is not the same gun. I
don’t know how you do it and what all you do but
tuning it was sure is worth the money. It’s a
totally different animal now and so much more fun to
shoot. Smoother shooting, the recoil is less with no
torque and much more accurate.
When looking at the returned parts I couldn’t
believe the cant in the factory spring and the seal
damage with only a few hundred pellets through it. I
can see where the seal was damaged when they
assembled the gun too but it was what you told me to
expect. There sure is a big difference in how it
shoots and feels now. You sold me a tuned B-20 6 or
7 years ago when you and James Kitching were selling
guns that I traded a few years back and this B-26
has brought back old times. I should have kept it.
This one isn’t going anywhere for sure…lol…
All I can say is thanks for the great job and
service.

Hey Charlie……….all I can say is “woowow”. I got me a
Gamo Shadow now that is a totally different gun than
what I sent and what a difference there is. I had no
idea it had this kind of potential. Smooth cocking,
no twang or vibration and the improvement in
accuracy at 35 yards is greatly increased shooting
dime size groups now when I do my part. And the
improvement in the trigger is unbelievable. Best
investment I could have made in a toy and I see why
they refer to you as the Gamo God. All I can say is

The 48 made it home today as expected. You have made
this old man happy (if you can call 52 old). I knew
that it could be improved but I didn’t know how
much. Now I know. Fantastic job and well worth the
expense although I must admit that I had my doubts.
I wasn’t sure it was the same gun that I sent it was
so different. But from everything that I have read
and everybody that I talked to, all said you were
the man to send it to.
It still is a bit heavy to cock but as you told me,
that would not be reduced much but is smoother
cocking and has less recoil and not nearly so harsh
shooting. It’s a real pleasure to shoot now. I also
like the way that you set up the closing pressure
when you cock the gun. I forgot to mention it in our
discussion and it always did feel a little sloppy to
me. But you caught it and fixed it during your
servicing. Thanks.
To anybody that reads this, I highly recommend
Charliedatuna. Its money well spent and worth every
penny of it. Excellent service, honest, keeps you
informed and a great person to talk to and deal
with.

Hi Bob,
I received the gun (RWS54) and I remounted the scope
and zeroed it in. The first immediate sensation was
that the cocking was light and smooth and the
trigger light and crisp. There was no spring
vibration or recoil. The gun then began to punch
holes that were touching and with lots of power; and
it is not even broken in yet from the tune-up.
Thanks, Bob, for the fine service. Just for the
record, this is an unsolicited testimonial that you
may use at your discretion. And further more, my
Gamo CFX will be next!

Subject: CDT tuned CFX...long, but good and is..
in a word....awesome!!! Got it back the other day.
First look out of the box I could see the Gold
trigger staring at me. Cool! Next, I picked the gun
up and realized the loose right piece of the forearm
stock that came with the gun was now tight thanks to
CDT. Now the gun was clean and shiny and tight. Here
is the pre-tune story on my CFX. 
Cocking the under-lever was rough, noisy and uneven.
Heavy recoil and "thwang and big vibration" while
pulling the trigger. Trigger pull very hard and
unpredictable. Although the CFX only had 400 or so
pellets through it at the pre-tune stage, I was
hoping for some better groups at that point with the
best shooting pellet at that time. I was leaning
toward the JSB preditor.
Ok,..now for the post tune from CDT
Cocking the under-lever was much easier, with very
little noise, (if any), and smooth as glass, from
start to finish. The heavy recoil, thwang, and
vibration is GONE. The new GRT trigger
is........AWESOME!!! What a difference!!!! I can't
begin to tell you what this trigger has done for
this rifle. Again, just like the rest of the tune,
the trigger is as smooth as glass. CDT also includes
detailed specs on your gun including gun care,
trigger specs and your guns chrony results before
and after the tune up, and more.
I had to post a pic of my CFX from CDT below and add
a few pre/post chrony numbers too. If you want a NEW
air rifle...sent it to CDT. The difference is not
night and day,...but midnight and mid-day!
BTW...I shot 4 different pellets through the CFX
today. JSB Predators still won the day. I will post
more results after my liberated CFX is " broken in
again".
CDT pre/ results:
Trigger Lbs pull ave. 5.8
Highest Velocity fps 878
Lowest Velocity fps 861
Ave. Ft Lbs Energy 13.90
CDT post/ results:

As you may know I received the CDT turbo-tuned and
new trigger from him this week. OK.....drooling
again.
I used Crosman 7.9 domes (from the brown box), JSB
predators, and Gamo Tomahawks. They all grouped well
with not one "flier". I looked around and found some
Gamo Rockets sitting in back of my pellet station as
I call it. I went outside and put some fresh paper
at 25 yds and grabbed a beer and returned to my
shootin station. First shot...dead center. I then
decided to shoot a 10 shot group with the rockets.
OMG....never...ever have I ever shot a 10 shot group
like this, (even with powder burners), and with Gamo
Rockets? The gun must like em. Going to Wally World
tomorrow to get some more! This rifle is now a class
one shooter thanks to the CDT tune+ trigger.
BTW....keep in mind that this rifle is not broken in
yet! Only 125 pellets since the tune. I can only
imagine what it will do at its peak .

I got my gun back today and now its way better. At
first I was going to send it back to Gamo until I
heard about you from other people so I figured that
I would send it to you. Anyways I was expecting to
get back a Gamo shadow 1000. What I got back was a
lot better than a Gamo. It fires more smoothly and a
lot more accurate. When I cock the gun I don’t here
grinding funny sounds anymore. If I would have sent
it back to Gamo they would have replaced it but
instead I got the turbo tune and now it’s like those
German guns. Now the trigger I love the trigger. I
had no idea that you could get the trigger that
light and I love how it’s square and not rounded it
gives me more feel. I thought the Gamo trigger was
okay but now I can say that it has a great trigger
and I owe that and the way it shoots now to Bob
Werner so thank you very much! And I would recommend
this tune and trigger to anyone.

he kept me informed from beginning to the end, which
was not long at all 1 day is all it took. When I
received my gun back I immediately took it out of
the box cocked it and at that time I knew that I was
in for something special. After sighting it in with
my new Barska 3x12x40AO scope I can kid you not I
shot five shots with each pellet touching each other
at 28 yards less than 1/8" from smashing the
bullseye. This is a completely different gun that I
have now, let me just tell you that the turbo tune
was well worth the money. Thank you Bob, now I see

Tuned Gamo 220
December 22 2006 at 7:52 PM
I wanted to share my experience with Bob "CharliedaTuna".
I was a little hesitant to drop another $180 on a
rifle that I was already disappointed in, but
decided to take the plunge. Am I glad I did! What
follows is the email I sent him right after getting
the gun back and testing it out...

Bob,
I just wanted to let you know that I got the rifle
back today.
Wow, what a difference! It is now so much quieter
than before. The new spring makes cocking noticeably
smoother and lighter. The trigger job you did is
fantastic - very smooth and light with no gritty
travel at all. Best of all, the recoil has all but
disappeared - just a mild bump is all that's left.
Before, it would twitch and jerk like a hip-hop
rapper doing the latest moves. Now it is very smooth
and gentle, with no rotation or sideways jolt. The
spring seems to make just a single thump as it
fires. Nice job!
It also seems to be much more powerful. I noticed
the chronograph results showed an increase of nearly
60 fps. The only downside to that is it now shoots
right through my pellet trap, whereas before it
would only dent the back plate. Problems like that,
I can live with!
My shot groupings seem much tighter, but that's just
using the iron sights. I can't wait to put the scope
back on, sight it in and see on paper just how good
the magic is that you put into this gun. There's
nothing like good old American craftsmanship from a
man that takes pride in his work. You certainly do,
as evidenced by the job you did on my Gamo.
Bottom line, I couldn't be more pleased. I am
looking forward to shooting at least a tin or two of
pellets over the Christmas holidays. This gun now
rocks! Thank you!

Subject: Shadow 1000 .20 Caliber................
Got up early this morning and went over to CDT's
house and rousted him outa da bed a 60am..Drug him
to his shop and through my new Wally World Shadow
1000 on the bench with a new Walthers Choked .20 Cal
barrel from Rich, AKA "Peterdragon"....
Immediately CDT's eyes got as big as eggs when he
picked up the barrel and checked the rifling and
choke out. He carefully ran a pellet through the
barrel with a dowel. Very slow until it popped out
on the bench. He picked it up and pulled down the
big lighted magnifying glass from over head. He
gazed at the pellet for a moment or so spinning in
his fingers and said, "the rifling is perfect on
this barrel". I looked at the pellet head outer
surface myself and there you could see I think lines
on the outer edge of pellet. I learned now what a
nice choked barrel is supposed to spit out..
CDT then called his Doberman out of the house and
told him to watch me till he was done. So I went to
the corner while Fritz laid starring at me for 4
hours.
While I was sitting for all that time, CDT was
exchanging the .177 Gamo barrel with the .20 cal
Walthers barrel. Giving the Shadow a complete Turbo
Super Tune with spring, GRT-III trigger, and custom
made spring guide, then deburring all parts, honing
the chamber tube, washing cleaning and blow dried
everything.
Then he took out seven containers with a different
lube in each. He then applied the different
lubricants to different parts of the Shadow just
like he does all of his tunes. He was using home
made tools that he made to apply lube meticulously
all over the Shadow’s working parts.
Well 4 hours later CDT he looked over at Fritz told
him to go in the house and called me over to the
chrony and said shoot the dang thing..
First thing I noticed was the barrel was a bit
bigger and the Shadow was a tad heavier but not
much. I threw in a pellet that Rich, AKA "Peterdragon'
had supplied with the barrel. Laid the barrel on the
chrony rest and fired. First shot was 683 but all
consecutive shots were between 728 and 783. As I put
in the pellets and shot, the numbers improved. We
put in around 15 pellets for chrony testing and come
out with about a 760 FPS average.
To say the least, I am very very pleased with the
outcome of the Conversion. Rich, AKA "Peterdragon"
had sent me a flawless barrel that converted very
easily. He also sent along a tool to use in order to
remove old barrel with and, pellets, muzzle brake
and allot of talent and workmanship. Thanks Rich and
thanks to CDT's excellent airgusmithing.
I have ordered 6 tins of Beeman FTS pellets and will
have some more information after the weekend.

Noted by Charlie: The GRT-III trigger was also
installed in Darryl’s CFX.

Bob,
I got the CFX this Saturday (I was surprised since
Saturday delivery is usually extra). I notice that
Gamo changed the CFX a little bit. The last one I
had didn't have a separate elevated scope mount and
the rotating breech was chrome plated. The new
rotating breech is some sort of sand blasted finish
on it. I think now only the CFX Royals come with the
chrome plating and machined in functional scope
dovetail.
In any case the new CFX that you TurboTuned is just
fantastic. This one feels like a truly precision
instrument instead of a toy. It doesn't even feel
like a "springer" it feels almost as if I am
shooting a .22 rifle with just a small recoil but no
twang or twisting. I have a friend with an FWB 124
and not only is the trigger better than his, but the
CFX you worked on appears to be more powerful, more
accurate, and smoother shooting. By the way, his FWB
124 originally had a Beeman tune and wasn't a bad
gun, but it was vastly improved with a Maccari
spring with heavy tar, and a new Maccari seal. Your
work on the Gamo has surpassed his tuned Feinwerkbau. 
While I can't say that you've transformed a Gamo
into a Feinwerkbau, you've made it perform as good
as one. Thanks for an outstanding job!

Subject: Quest 800x Post tune by Charlie
Posted 7/23/2006 10:22 AM (#2191)
Just got my Quest sighted in after it's return from
Datuna'. For all of you that know the type of work
Bob does it goes without saying, but to those who
are thinking of having a tune done to their springer
read on....I sent my rifle off to Bob, AKA
Charliedatuna, for a super tune and trigger. What
came back was an entirely different class of rifle.
The trigger was the highlight of the tune. All you
have to do is think and the trigger breaks as though
it was a delicate glass rod. No movement other than
the initial take up which you have to really be
concentrating to feel but it is there. The rifle is
quieter and more powerful than before with an
increase of 80 to 90 fps. Now for the good part if
you can believe it could get better. After the
initial sight in which only took 6 pellets it
preceded to place all pellets in a ragged hole
easily covered by a dime at 15 yds. These are just
the first shots at a short distance to further
refine the scope adjustments. Not having any more
time yesterday I cleaned and put the rifle away.
This morning I woke to the sound of a bird feeder
destroying fiend who was doing his darndest to put
an end to the just newly purchased replacement to
the last feeder that was hanging in the same spot a
few days earlier. I snuck around to the side of the
house and unleashed the fury of the Charlie tuned
Quest and with surgical precision placed an RWS
hobby pellet into the offending intruders melon and
it preceded through and out of its computer
rendering its motherboard inoperable. Needless to
say, the rifle did its job. I am more than impressed
with the rifle's performance. The tune made the
rifle so much smoother, took away the shock and
twist associated with the firing cycle. It was well
worth the money spent as I received a rifle that far
surpassed my expectations. If anyone is considering
a tune from Bob, don't hesitate any further. I can
recommend Bob without question. My rifle is a gem, a
far cry from what it was. If anyone has any
questions about this rifle feel free to email me. I
will try to answer them if possible. I do have
before and after's also if anyone would like to see.

Hello Bob,
All I can say is Awesome! Oh what a difference a

and it shoots. What a pleasant surprise. I can feel

nitty gritty with this thing. Thank you Bob, it was

I think I've found a piece of heaven...
PorridgeWeasel
and it's my just returned Shadow 1000.
I sent it to CharlieDaTuna for a Super Tune and GTX-II
trigger after about 2000 rounds. Now, I've read
plenty of reviews of his work and there were
comments like; "It's a different gun",
"Unbelievable" etc. All I can say is, "Wow!"
I had a chance earlier today to shoot it outside (2
shots) and my reaction was (truthfully) a continuous
giggling "Oh my God!".
About 15 minutes ago I came back upstairs after
putting my BSA 3-9 X 40 back on and sighting it in
at 10yds. I still can't believe what I was able to
do. 7 shots inside a dime and one of them was off
due to my inexperience with the trigger. 4 of them
touch each other with one that shot thru THAT bunch.
I too must now say that I think Charlie just
switched guns on me and gave me something different.
Something amazing.
Outside I was struck at the reduction in noise. I
also noted the crazy azz trigger pull.
After firing about 30 shots indoors I noticed
something even better. A tremendous reduction in
recoil and no spring twang sound. None. Just a solid
"thunk" followed by a wail of pain from my pellet
trap. The combination of trigger and reduction of
recoil is truly amazing. The amount of strength
required to cock the gun is also (in my opinion)
significantly reduced as well as smoothed out. No
where near 38lbs.
Now for all you number crunchers out there, the
"info".
Pre-tune Chrony was:
884,872,893,886,885,897,878,904,899,882 with an
extreme deviation of 32
Post tune Chrony was:
926,923,929,925,931,927,930,924,933,928 with an
extreme deviation of 13
Avg. Ft lbs of Energy went from 13.84 to 15.13
He used 7.9g Gamo pellets for the test.
Average trigger pull pre-mod: 4 lbs 7 oz
Average trigger pull post mod: 1 lbs 10 oz
I am MORE than satisfied with his work at this
point. I'll keep youz up to date as I re-brake it in
if there is enough interest. I will chrony it again
with my various pellets probably too.
Short end of the long story at this point is, if you
are thinking of getting a professional tune up on
your gun.....Think of Charlie. He certainly won't
steer you wrong.

The following information on my CFX Royal .177 is

3-9x40 AO Mil-Dot Scope with R/G LESCP-394AOMDL.
This scope is very well made and very clear.
Adjustment is very easy. Used Accushot one piece
scope mount.
I then sighted in the scope adjusting the parallax
to 10 yards. I was using RWS Superdomes. At this
point I started to test for groups. I noticed that
the CFX Royal was very rough and noisy, but trigger
felt comfortable. I was getting very irregular
groups at 10 yards inside the 1” circle and I could
not get a bull’s eye at that distance. Then I
grabbed my CFX .177 Synthetic that has been tune by
CharlieDaTuna with a GTX trigger. Adjusted scope and
bingo, I was hitting right on the bulls eye with the
first shot. Then I picked up the CFX Royal .177
again kept trying for that bull’s eye, but no luck.
I placed my target stand out at my 40yard marker.
Fired my first shot at 40 yards with the CFX Royal
and was no where near the bulls eye.. I always use
those 5 ½” Shoot N See targets for initial scope
adjustment and then go down to the 2” Shoot N See
targets. I was able to get the groups with in 3” at
this point but lots of them were scattered around
the target. Nothing consistent. I ran through about
200 pellets. I then broke out some other pellets and
tried again and again and things just got worse. I
had fired around 600 pellets by now so I took it to
Charlie. I am sorry I did not keep the old target to
show you but I did keep the target that I used after
CharlieDaTuna did his TurboTune on it. I did not
have him do a GTX trigger on this CFX Royal .177 at
this time. Click on thumbnails to see larger image:
Could not wait to get it home to check for accuracy.
Finally I installed the Leapers 3-9x40 AO Mil-Dot
Scope with R/G LESCP-394AOMDL and sited it in for a
10 yard target. Bingo was able to snag a bulls eye.
And the at 40 yards. Bingo, it felt so goooood. The
CFX Royal was like a different springer this time.
Yes, CharlieDaTuna had done his magic on another one
of my springers.
I am a novice with air gun springers and have no
idea how to tear down one for maintenance. Maybe
someday but right now I am enjoying the sport of
shooting targets for accuracy thanks to Charlie.
Pre-Tune opinion of the CFX Royal .177…… On a scale
from 0-10 – 0 being the poorest. This is based on my
experience with Gamo Springer Models only.
Noise = 7 Dieseling = 5
Recoil = 7 Trigger = 8
Accuracy = 6
Post Tune- CharlieDaTuna, Tune Up
Noise = 10 Dieseling = 10
Recoil = 9 Trigger = 9
Accuracy = 10
As some of you know I have bought a few Gamo’s since
I have joined this great forum. I do know this that
every single one of them have been tuned and GTX
triggers installed on some by CharlieDaTuna. The
difference has been night and day. I really think
that Gamo has a great rifle but they did not finish
the job with detail of tuning.
CharlieDaTuna has made this sport for me a wonderful
experience. I honestly do not think that if I had
not sent my first springer “S1K” to CharlieDaTuna
that I would not be here on this forum writing about
this fantastic experience with a well tuned springer.
A personal thanks to you CharlieDaTuna for all u
have done.
I thank all the rest of you for all the help and
advice that you have been so willing to give me.

Charlie, got the Beeman today. Wow. Whole different
gun. I put the scope on and sighted it in. The
cocking is very smooth instead of sounding like it's
grinding something up every time. The trigger is
great, nice and crisp. The spring has a nice thud
instead of sounding like it's flopping around in
there. Thanks!
I'm 62 and this is my first pellet rifle other than
a daisy. While You were working on it I bought a
couple of QB-78's in 22, also after some reading, I
got a B-26, which I'll need your magic on sometime
soon.
Well thanks, Charlie for making a rifle that I
didn't think was to whippy when I got it into a
great shooting rifle.

Been an Exciting day Here at da Gamo Ranch…. Read
Review
April 5 2006 at 7:39 PM Gene C
On Tuesday I carried my Shadow 1000 over to Bob’s
house “AKA Charlie Tuna”. Forgot to ask him how he
got dat handle. lol. Anyway I went to Columbia, SC
today and on the way home, Mr. Tuna called me on my
cell phone to let me know my Shadow 1000 was ready
to pick up.. wooo hoooo. Just happened to be going
by his place on the way home so I stopped and picked
up my Shadow. This was the second time that I had
met Mr. Tuna. I have to describe him to some of you
guys that have not met him before. He is a very
meticulous person. I could tell right away by how is
Air Gun Shop looked. Everything there was
immaculate. You could of eating off da floor and
benches. He has some fine machines in his shop.
Drill press, Lathe, etc. and it all looks like new.
Now about Bob. My impression is that he is a decent,
honest kind of guy. A man’s man sorta speak. He
loves what he does and I notice that he has a fine
collection of old and new rifles and pistols. The
rifles he has restored and looks better than new.
(Really). I am very fortunate to live near him.
Now about my Shadow 1000. It was like a completely
different air rifle than I carried over there on
Tuesday. Since I have had the Shadow, I have grown
attached to shooting targets with it. I thought it
was pretty accurate at 30 yards before I carried
over to Bob. One thing that I did not like was the
trigger. Was not smooth or predictable, not to
mention the noise of the spring etc.
I carried the Shadow home and WOW, there was my New
CFX .177 waiting on da porch for me. Already I could
not wait to shoot some targets with the Shadow and
now I wanted to open my new Toy… LOL.
I put my BSA Scope back on da Shadow and opened da
new CFX up. Weeeeeeeeeee!!!! Set up me targets and
sighted n me scope.
Let me tell you this. The Shadow is so nice now to
shoot. The trigger is perfect for Targets Practice
and I was hitting da dime 9 outa 12 shots. The
Shadow sounds like it has a silencer on it now, and
no noise outa da spring. VERY VERY VERY Smooth
action. The Trigger pull is Damm nice.
Now for the CFX… he he…. I love it also. I like da
trigger the way it is. It is quieter than the Shadow
was when I got it. One thing I noticed right away
after cleaning it up and takin 20 shots at fresh
target at 30 yards without a scope. I hit da dime 14
outa 20 times without a scope. Could not get that
many from da Shadow without da scope the first time
I shot it.
Here is the writing on the wall Guys. Before and
After Charlie’s Trigger Mod and Turbo Tune. Check
out the difference. Amazing Would I recommend
Charlie Tuna for Air Gun Smithing? DAMM RIGHT I
WOULD……….

B20 22 cal back from charlie
March 9 2006 at 10:30 PM James Morrison
I got my b20 in 22 cal back from getting a turbo
tune from CharlieDaTuna and I’m totally blown away
with this gun and I can’t believe this is the same
gun that I sent. I just have one thing to
say...WOW…what a difference from I sent to what I
have now. Talk about night and day. The tune sheet
that was provided with my gun said it all. I still
can’t believe this is the same gun that I sent him
and that this gun had any power from looking at the
old parts that were with the gun that he sent it
back. Now it’s more smooth accurate and has plenty
of kick. Just what I wanted. He will be getting all
of my future tunes as well as my friends. I’m going
to spread the word about him and his work that’s for
sure. Thank you very much. The trigger is awesome
and all thanks to CharlieDaTuna.

B30 review finished (results)
March 2 2006 at 5:19 PM
UPDATE: Review Post-Tuned
Wow, fast turn around Charlie! Just got the B30
back. Charlie didn't have it very long and he
communicated nicely through the process. As soon as
I got it I mounted a new Tasco Airgun Scope 3-9X32
with AO and target turrets on it. I took the chrony,
predator pellets, Eun Jin pellets, Gamo hunters, and
some field target specials outside. I had to shoot
it first just to see how it felt. I was
concentrating on the trigger pull more than
anything, so I didn't even notice till after the
next shot that the recoil was so mild. Just the
standard "thunk". Very smooth and no spring twist at
all. At least that's what if felt like. David
McMillan was over here, so he shot it. I said "what
do you think?" He said "Great gun, smooth, not harsh
and no twang." I'm pretty sure he wants one now So I
set up the chrony and ran FTS through. 740fps
average with very little variance in velocities.
Nice. Gamo hunters were 730 avg., Eun Jin (very,
very heavy) went 466 fps. That surprised me that I
got that much out of them. I felt the spring really
take a nose dive on those, so that's the end of
shooting those babies. The Predators shot 707
average. Now to shoot some groups.
The trigger is much better than before. Short first
stage, short second stage. Charlie gave me a 4lbs
trigger, but sent instructions on replacing the two
existing trigger adjustment screws with longer ones
to get it even better. I'll probably do that, but I
really don't want it much lighter since this gun
will only be used for hunting pests.
Right now, the B30 is smokin’ a bit out the barrel
after shots, but Charlie sent a good instruction
sheet explaining that, about the lubes creeping
forward for a bit. He also mentioned that when the
seal set's in good, I may gain, up to, an additional
3% on velocity. This is the hottest firing .22 I
have had to date and was mainly looking for
something over 700fps, preferably 750. So it fit's
that bill even if it lost or gained any additional
velocity.
Well, that's it. I now have the .22 hunter I have
been wanting for quite sometime. I'll put a sling on
it, pellet holder and call it good. Now I gotta
baptize it in some Jack Rabbit blood.
Recommendation - Get one, get it tuned by Charlie
and go get some vermin

Truman:
I've own several Gamos and sold all but still kept
my handsome Stutzen. Compared to the high end spring
guns like Beeman, AA, Webley and Theoben, Gamos fall
short. But these are actually pretty good. Here in
Puerto Rico, that is the best you can shop around
and they're expensive. For example; a Hurricane 1250
for $650.00, go figure...
If you like your shadow 1000, send it to
CharlieDaTuna for a tune and a new GTX trigger. I
did it with my Stutzen and the thing is a totally
different gun now. Very, very nice. What can you
expect form Charlie's tune? A bit power increment, a
sweet shooting cycle and overall smoothness, a solid
thud instead of the spring twang. Charlie uses
Maccari internals. The new GTX trigger blade is a
huge improvement over the factory trigger blade.
Seriously, you should try it.

An E-mail from Jason C ….Gamo 890 1/29/06
I am an accuracy nut when it comes to shooting my
high powered air rifles and I just really enjoy
shooting. I got into shooting my neighbors air guns
because we could shoot right here in town without
having to leave the area unlike high powered rifle
shooting. He had a Gamo shadow and a Gamo 220, they
were very fun, however the triggers were both
horrible and he had major trouble with scope
slippage on both guns. I really wanted an air gun
but did not want a Gamo at first because of the
trigger, but when I heard about BOB WERNER
(CharlieDaTuna) I decided to start looking for a
used rifle because from what I had heard he made
them better than new. Well I found a Gamo 890 and
sent it off right away to him. I took advice from
his emails when I asked questions and the great
advice from his website. I think you could get all
the answers to your questions from his website
especially by clicking on air gun docs.
Any way, when I sent it Bob communicated to me when
he received it, started working on it and when he
sent it back so you never have to wonder or worry. I
got whatever he recommended and the GTX trigger mod.
The first day I shot my gun after he had worked on
it; my neighbor was embarrassed to shoot with me. My
groups are typically half the size of his. I found a
pellet now that shoots a ten shot group at 45yds
that is less than two inches in diameter with five
of those shots hitting a nickel size bull!!! I know
that when I shoot my neighbors gun, the trigger pull
alone practically makes it impossible to shoot this
accurately.
My trigger now pulls at less than 2lbs and my gun
shoots pellets almost 100 fps faster on average than
when I sent it to Bob. In my opinion this gun is
worth more now than a high dollar RWS or most any
other gun from the factory.
I also want to let you know that Bob Werner is not
just a great business man who does great work; he is
an overall nice, good person. It shows from all the
emails and the phone conversation I have had with
him. I advise you all if you are serious about your
air gun to send it to Charlie the tuna and you will
get back a gun that is better than the factory can
make it brand new!!!!

Gamo - NRA Special Ed. (tuned)
December 28 2005 at 3:13 AM
Bought a NRA Special Edition Gamo and sent it
unfired to CharlieDaTuna for his high end tune and a
gtx trigger. Got it back from Charlie in like a week
and a half or less.
Not having fired it first, I can't judge a before
and after comparison however, let me say this. It is
"in my opinion" a nice looking package, light
weight, ambidextrous (I'm a lefty),very smooth to
cock and fire, quiet at the muzzle and with a
definite lack of spring noise or twang as compared
to my ole Crossman Challenger that was made in West
Germany many years ago for Crosman.
It is accurate and shoots in the low to mid 900 fps
average with 8ish gr pels. which probably puts them
in the 14 to 15 fpe bracket. A real pleasure to
shoot. Still testing pellets, but I'm very impressed
so far and am expecting more fpe and equal or better
accuracy with mid wt. or heavier pels at lower
speeds.
I can only attribute this to Charlie's magic,
judging from previous threads I've read referring to
some of the shortcomings of Gamos expressed by other
readers. Only time will tell about the reliability,
but isn't that true with any brand new gun. I don't
anticipate any problems after Charlie worked it
over.
Charlie is good people and a great guy to work with.
He puts his all into doing you a good job and I
think he really enjoys his work. Thanks Charlie.
Tuned Gamo 220
December 22 2005 at 7:52 PM
I wanted to share my experience with Bob "CharliedaTuna".
I was a little hesitant to drop another $180 on a
rifle that I was already disappointed in, but
decided to take the plunge. Am I glad I did! What
follows is the email I sent him right after getting
the gun back and testing it out...

Bob,
I just wanted to let you know that I got the rifle
back today.
Wow, what a difference! It is now so much quieter
than before. The new spring makes cocking noticeably
smoother and lighter. The trigger job you did is
fantastic - very smooth and light with no gritty
travel at all. Best of all, the recoil has all but
disappeared - just a mild bump is all that's left.
Before, it would twitch and jerk like a hip-hop
rapper doing the latest moves. Now it is very smooth
and gentle, with no rotation or sideways jolt. The
spring seems to make just a single thump as it
fires. Nice job!
It also seems to be much more powerful. I noticed
the chronograph results showed an increase of nearly
60 fps. The only downside to that is it now shoots
right through my pellet trap, whereas before it
would only dent the back plate. Problems like that,
I can live with!
My shot groupings seem much tighter, but that's just
using the iron sights. I can't wait to put the scope
back on, sight it in and see on paper just how good
the magic is that you put into this gun. There's
nothing like good old American craftsmanship from a
man that takes pride in his work. You certainly do,
as evidenced by the job you did on my Gamo.
Bottom line, I couldn't be more pleased. I am
looking forward to shooting at least a tin or two of
pellets over the Christmas holidays. This gun now
rocks! Thank you!

An E-mail from Tim Nov. 12 2005
Hi Bob,
I just wanted to let you know how happy I am with
the results of the tune and trigger upgrade. The gun
used to vibrate and jump in my hands, requiring
great concentration and a little luck to hit the
target. After the tune, it seems like a different
gun. The vibrating twang has been replaced by a
solid “thwack” with slight recoil. Now if I miss the
target, it is operator error, not the gun jumping in
my hand. Thanks to you, I am now totally accountable
for my misses,
As a note to anyone with a Gamo gun, even if you
just pulled it out of the box, send it to “Charlie”
for him to work his magic. You will then realize the
full potential of the gun. Get the trigger upgrade.
The stock trigger pulled at over 6 lbs, under 2
after the upgrade. It feels like butter, so smooth
and very predictable. I also gained about 50 fps. I
had been pricing other guns, in the $500.00 plus
range, since I am now hooked on airgunning. I
thought I would have to spend that much to get the
kind of performance that I am now getting with my
gun, a Gamo Hunter 440. My groupings have gone from
around the black to inside the black on a consistent
basis. It is well worth the money spent. He is very
professional, letting you know the status of the gun
at each stage. Just do it, you won’t regret it.
Thanks again,

Legacy tune-up
January 14 2006 at 11:58 AM springernut springernut
I just received a Benjamin Sheridan Legacy 1000 for
Christmas. I had one of these over 20 years ago that
was stolen and never replaced.
After getting it out of the box, I was kind of
disappointed to see all the plastic parts that used
to be metal, but figured what the heck, lets shoot
it. The power is definitely still there, with all
it's recoil, but what really surprised me was just
how much the quality of the trigger had
deteriorated.
After finding out that these things can be tuned up,
I sent the rifle to Bob, aka "Charlie da tuna" for a
super tune, and trigger tune. I must say that he did
a great job with it. The spring twang has been
changed to a dull thud, and a lot of the recoil
twist is gone. The trigger is now much improved
also. It had a 7lb. pull to start, with lots of
creep, and the release was pretty unpredictable.
Now, it pulls at 3lbs. 10 oz., has little or no
creep left, and releases predictably each time.
I just wanted to tell anyone who is considering a
tune, to get it done. Bob took real good care of me.
He does what he says he will do, for what he says he
will do it for. He runs a good honest service, with
fast turn around time that is a great value for the
money he charges.
The tune-up made it a lot more fun to shoot this
entry level rifle. Even though Bob claims to
specialize in tuning Chinese Springer’s, he did a
great job with my Legacy. I would recommend his work
to anyone.

GTX trigger mod.
August 10 2005 at 1:37 PM
I wanted the NRA Gamo 1000 rifle currently being
offered in our "American Rifleman" magazine but had
experienced the Gamo triggers and was hesitant. An
inexpensive line like Gamo had to cut costs
somewhere. It came with the territory. Then I saw
Charlie Da Tuna's GTX trigger mod for the Gamo line
and orderd the rifle and trigger mod. This makes the
Gamo 1000 a match rifle in sporting guise. I have
only had 2 match rifles and 2 match pistols with
better trigger pulls. Light and crisp at just over 1
pound makes it my favorite springer. I have several
HW's with their famous Rekord trigger and it can't
compete with the GTX. Gary
And the e-mail Gary sent to me: 8/10/05
Boy, oh Boy! This GTX trigger mod for my NRA Gamo
Shadow 1000 is amazing! Better, by far, than HW's
rekord trigger. Such a simple fix and a perfect
trigger pull. I wish all my guns, rifles and
pistols, firearms and airguns, had this trigger.
I'll be referring all of our membership with Gamo's
to you. Springers are hard beasts to tame and this
trigger makes mastery simple. The most surprising
part is that this is in a sporting springer.
Amazing!
I have posted my raves on reviewcentre in answer to
a guy who liked his Gamo Shadow but hated the
trigger. Several other posts had mentioned to him
that you had a trigger mod for it, but no one had
actually tried it. I told him it would be the best
$37.50 he would ever spend.
I'll be back for more of your products and services.
Every once in a long while I'm impressed with a
product and I certainly am now. You're a good man,
Bob, and thanks for the next best thing to sliced
bread.

Air rifle tune-ups by Charlie
July 11 2005 at 5:05 PM Chris
I just received my Mendoza .177 the other day after
having Charlie (CharliedaTuna.com) do one of his
Turbo Tunes on my rifle. Prior to sending it in, the
rifle had lost a lot of its power and accuracy, so i
figured it needed some work. Charlie installed a new
spring along with a new seal, and completed the rest
of the tuning on the rifle. The results were as
follows: Prior to the tune, it shot approx 450 fps
with an 8.3 grain pellet. After tuning the gun, it
now shoots 760 fps, shooting dime size groups at 25
yds. Aside for restoring the umpf in this old
shooter, he also eliminated all spring twang.
Furthermore, after deburring all of the parts and
completing the tune, the gun is much smoother to
operate, and is more solid now than when i first
purchased it. I'm really glad i decided to tune my
old rifle instead of buying a new one. The gun is
primarily used for target shooting and pest control,
and after having it tuned, the pigeons on my deck
are in deep trouble.
To anyone out there who's thinking about sending
your gun to Charlie, i can highly recommend that you
do...It'll never be the same again...in a very very
very good way.

Tuna'd Gamo 220
May 14 2005 at 2:27 Pm Rob
OK, so the Gamo isnt a Chinese gun, but the guts are
similar to a B19 from what I've read. Also, I'm sure
much has been said about Charlie
www.charliedatuna.com on these forums, but I have to
put in my two cents.
I got my Gamo 220 back today from Charlie...wait..no..I
didnt get MY Gamo back...I dont know what I got
back, because what I got back was NOT what I sent
him. This thing is amazing. I called Charlie to let
him know about the gun I was so excited. I could not
imagine how much better the Gamo would have turned
out. The guy does magic.
Before the tune up I was getting around 898 fps with
Gamo hunter pellets and about 756 fps with CP Heavy
pellets. ....after the tune.... 955 with the Gamo
Hunters and 831 with CP Heavies. Thats amazing. The
gun now far exceeds my RWS 34 in velocity and
smoothness of operation. The 34 goes next. If I can
get 1/4 the results with the 34 as I did with the
Gamo, I'll be happy.
Again, hate to sound like a commercial here, but for
anyone who hasnt had a tune, it will be the best
money you can spend on your springer. I just cant
say enough about what Charlie can do with these
guns. Also, I also had the MK-1-GTX trigger
installed. Man what a difference.
Of course, its raining now, so I cant test accuracy,
but I've already shot about 50 pellets through it
out the door smiling with each shot.
Thats sounds Great I got to get one of my B20s to
him!!
May 14 2005 at 11:06 PM DAckerson
Was that a Turbo Tune or the basic tune. I can't
imagine a Gamo needing a Super Tune. I think I may
Turbo tune the B2022 and GTX trigger one of the
Gamos maybe the S1k .177.

Tune
May 14 2005 at 11:25 PM Rob
I think it was the Super tune. Whatever he
recommended, I had him do. Just email him and he'll
treat you right. I hear the B20's turn out really
nice. I was planning on getting one in .22 to send
to him, but my Gamo is almost getting 17fpe now in
.177 so I'll stick with it. Going to have him do my
RWS 34 and 54 as I get the cash. Cant wait to see
how they turn out after seeing what he could do with
a beat up Gamo.

Charlie,
Just wanted to thank you for what you did to my
GAMO. I absolutely Could not believe it was the same
gun. The gun was totally different, smoother, easier
to cock, much quieter, more accurate and a complete
pleasure to shoot. The new trigger was amazing, it
made all the rest of the work you did even better.
Since I've got it back I can't put it down, must
have shot it around a 1000 times. And it just keeps
getting better.
Your service was extremely professional and very
personable. You made me fell like I was your biggest
customer. Thank You again and I'm sure I'll be a

Charlie,
I received my GAMO Hunter 440 back from you today
and after the first shot I knew that you returned to
me a quality shooter - much different than what I
sent to you. The cocking is much smoother and even
though the sping is more stout , it was fairly
effortless because of its smooth operation. Next,
when I pulled the trigger - gone was the annoying
massive 1st stage creep and that made the trigger
feel cheap - and in its place is a quality MkII wide
aluminum trigger that pulls light and smooth - I'm
not sure what I like the best, but this part is up
there. Probably the best part of all is the sound
that my gun makes now - hard to explain because I
haven't ever heard anything like it come out of a
pellet gun before. Its a sound that makes you know
that there is some real quality behind it - not a
rattle coming out of the spring like there was
before - its almost completely silent in ! ;spring
release, and is such a strong and powerfull pop that
it shocked me the first time and then just made me
grin. I was definitely surprised at the sound coming
out of the barrel. I'm very impressed with your work
and what you have made my gun into. I shot about 50
pellets tonight and I'm grouping them nicely in
about a quarter sized circle at 10 yards - and its
not even close to being broken in. Thanks again
Charlie - and for the quick turn around time.
Sincerely,
Mike Stalling

An E-mail from G.H.
Bob,
Just wanted to say thanks again for the great job
you did on my Gamo Shadow .22. The new trigger is
totally different and absolutely great. At first I
thought it might be a little light for a field gun,
but after a brief re-adjustment period I love it.
Cocking the gun is also noticeably smoother.
I've mounted a Leapers 4x32 mini AO Scope and have
shot about 300 various pellets. I'm lucky that it
seems to like whatever I feed it. I haven't had the
time to get out the sandbag rest and find the one
pellet that possibly may wring out the last fraction
of accuracy, but for offhand field shooting I'm very
pleased. 
In the last week I've dispatched 2 Copperheads and a
big Water Moccasin with head shots. It started when
my wife had walked over to where some neighbor kids
were shooting at one of the Copperheads with a BB
gun (without success). She laughed at me when I went
and brought out the Gamo saying there was no way I'd
ever hit it. One shot later she exclaimed " wow, you
blew it's head off, I'm actually impressed". The
kids also seemed surprised that an airgun could be
that accurate.
I'm sure this Gamo Shadow .22 will be around for a
long time.

cheaply built rifle finally broke, and I was
wondering if I should buy a new TF99 or have mine
tuned. I decided to have it tuned and im glad I did.
My rifle was in sad shape when i sent it to charlie,
it was used and abused. Charlie really did some
amazing work! (new spring, all new synthetic seals,
spring guide, completely reworking the trigger and
compression cylinder-and not to mention other tricks
he has picked up over the years) My rifle was
shooting around 499 fps with 15.4 grain gamo hunter
pellets with a trigger pull of just over 6 lbs.
before the turbo tune. After the turbo tune my rifle
shot an average of 735 fps with a trigger pull of
just over 1lb. Thats right one pound! My rifle is
shooting better groups than it ever has. I love it,
im much happier with a tuned rifle than a new one.
For anyone who is considering a tune, it is well
worth it.
Thanks again,
Trent Thompson

Post response:
Good for Charlie. All that and from a gun that's
advertised at 900fps! D R
Post response:
It depends on the pellet and spring. chinese web
site......of the company that builds them states
675fps for the .22 cal qb36-2. (Edit: same gun as
the TF-99)

mine does 840 with cp with the Maccari spring setup.
mr Werner shot it a while back and can tell you alot
about the chinese powerhouses with Maccari springs
and quality seals. These aren't little girly guns.
my gf won't cock it more than 3 times before she
says she wants to shoot the fwb300.
these are big stout guns for big stout shooters.

RE: RWS48
What I have to report is this...
Oh my. I'd forgotten how the rifle felt when new;
tight but more precise (now). There must have been
an ongoing deterioration in its performance that I
had gotten used to. I can recall specific moments
(in the field) when it got a little more rough
(metal to metal), but always seemed strong till the
end. I always felt like I was chasing the scope
setting. Now I can see. The velocity (and accuracy)
must have been steadily decreasing with each new
symptom of the cycle and, after viewing the returned
spring and guide, I can see why. 
With limited time on workday nights, I lack
concentrated shooting periods. This week end
however, will be the real trial.
The rifle is "night and day". Feels like shutting
the door on a new vehicle as opposed to the 1961
Mercury Comet. I thank you for your skill and effort
on my behalf.
Once I get some time under my belt I will confirm
what I already suspect. The gun is stronger,
smoother and more consistent. When I report that
confirmation I promise to be less verbose.
Kindest regards;
Mike

Now this is a B-22 March 27, 2005
Well. i,ve shot the hell out of the b22 broken peace
of crap that i sent you. Found the sweet spot for
the trigger. I'll now put the gun you sent me back
against any rws or beeman 22 caliber, its that good.
Expect more business in the future. I cant thank you
enough, you have turned a broken rifle into a
masterpiece.

Tuna-Shadow Supreme
March 12 2005 at 11:03 AM
One of those brown trucks that will never win a drag
race brought me one of those long, thin packages
yesterday. Of course, I was at work and couldn't
open it. What followed was four hours of agony until
I pulled into my garage and sliced the tape to
reveal my finely-tuned black beauty. She'd just made
the pilgrimage to the Da Tuna Finishing School where
she received the works, including a Tarantula and
that new trigger. I carefully stuck a few of the
quarter- sized adhesive targets on a half-inch scrap
alder plank which I put at the ten-meter mark on my
range. I proceeded to cock and fire a few shots, and
I was blown away: This couldn't be my poorly-behaved
Shadow; she cocked effortlessly, the trigger pulled
like a feather, and there was no vibration. I
drilled the target each time and walked out to the
plank. The shots were passing through the wood. I
was using the RWS .177 Superpoints. This has to be
one of the best tune jobs in modern history. The
firing vibration before the tune left me feeling
like I was going to lose some teeth. Now, it's
probably the smoothest shooter in my closet, even
with the synthetic stock. If you do what I did,
you'll be happy with this Wal-Mart orphan. You may
even fall in love. Mike

El Gamo Shadow 1000 meets CDT Farrell Bramlett
2-18-05
I purchased my first air rifle at Wal-Mart, El Gamo
Shadow 1000, and it shot great. The spring lasted
for about 10,000 shots or so, and as it reached the
end of its life I learned about having factory air
guns tuned.
While reading air rifle reviews I learned about
Robert Werner, who may be better known as
Charliedatuna, air gun tuner that is. I sent my Gamo
gun to him and when I received it back I was more
than pleased. The cocking action of the gun was much
smoother than from the factory. The velocity I now
receive from my gun is better than before as I used
to watch my pellets approach the target. He even
reworked the trigger free of charge. I highly
recommend having your air rifle tuned as you will
see a noticeable difference in its performance. The
turn around time on my tune was good as he received
it early one day and mailed it back late the next.
Robert kept me posted as to what problems he found
by way of e-mail. When I received my gun all I had
to do was mount my scope and I was ready to go. He
does good work and is honest with you about what
your gun needs. I am still in random contact with
Robert asking him questions as he is much more
experienced about air guns than I; and he doesn't
mind answering my questions. You can reach Robert by
e-mail and he can help you. 
I have now put about two-hundred-fifty shots through
my gun since tuned and it is doing great, and I
can't wait until the break in time has passed as it
will only perform better. Having my gun tuned was a
good idea for me and it has made my days in the
field a little more enjoyable. And all avid air
gunners know a day out shooting should be a pleasant
relaxing experience.

The Beast has been tamed! (B-21)
February 10 2005 at 3:30 PM
Purchased a B-21 from FunSupply and sent it off to
CharlieDaTuna. Turn around time was exactly 1 week
from the time is was sent. Bob called me at home the
night he received the B-21 to talk about my
expectation. It now shoots smoother than my old
HW55T. There is little to no vibration and is only
expected to get better. I had told Bob my interest
was not in velocity, but accuracy. I got both. Bob
is a miracle worker.

TF99 and Tuna
January 19 2005 at 12:49 PM Trevor
Charlie has made a believer of another Chinese
airgun shooter! I had sent him my TF99 just after
Christmas for a Turbo Tune. What a difference in the
shooting quality of my gun. Before I sent it to him,
I put a few shots through it to have something to
compare. The gun had a rough trigger and an awful
twang when shot. I trusted all you Tuna lovers out
there and sent it off for the tune. Twenty four
hours later the gun was on it's way back as were
e-mails letting me know how my baby was doing.
Excellent service to say the least. When the gun got
back to me, it was out to the range. What I found
was a completely different gun. Smooth cocking,
smooth predictable trigger (factory trigger, GTX
trigger mod does not work for TF99's) and no spring
twang! It was a investment to do the work to an ok
gun, but now I have a great gun for hunting and FT.
Oh sure you think with his help, and directions on
his web site, you can tune these guns up yourself,
but, this was no B-3 or fastdeer. It was money well
spent. He is a master and knows what has to be done.
If your thinking of doing a tune with Charlie, go
ahead you won't be disappointed!
