Charlie Da Tuna Trigger GRT 4G Gamo Only

This 2 stage trigger from Charlie Da Tuna is perfect for Gamo airguns, it increases your accuracy a lot!

This 4G triggerset has an extra cilindrical pen included. This is only for certain models of Gamo. Check if you need this before ordering. But: Do buy this great tune trigger! It will give much more pleasure and accuracy!

Here's the installation explanation:

The GRT stands for (Gamo Replacement Trigger blade). The 4 stands for (For) and the final G stands for (Gamo) Therefore'. GRT-4G.

The GRT-4G trigger blade is designed strictly around the new later model Gamo air rifles that now use the plastic trigger module. THAT INCLUDES THE NEW SAT TRIGGER. If it has the plastic trigger, it would use the GRT-4G trigger blade. The geometry and design does not lend itself to any other application and cannot be used in any other guns at this time. It will work in any of the Gamo spring powered rifles or gas ram rifles including future modifications to gas ram.

Why design the new GRT-4G trigger

With the earlier model Gamo air rifles (and also all of the Gamo airgun clones), one of the big issues was the terrible trigger. It had a very hard long pull and you never knew when it was going to let off. It utilized the Theoben/Gamo trigger design and it was one of the biggest drawbacks to the shooters accuracy. The shooter is always concentrating on the trigger and not the target and it is almost impossible to keep from pulling the gun off target when shooting the gun.

The new Gamo factory trigger design has all of the same issues that the earlier Gamo model guns had and many say that it's even worse. This new factory trigger change is in all of the newer model Gamo air rifles and we don't expect any changes in the near future. So. you don't need to contact me to ask if the GRT-4G fits in a particular late mode Gamo. It fits all of the late model Gamos with the plastic trigger.

The GRT-III trigger was designed to resolve the early model Gamo trigger issues and the GRT-4G is now the solution for the late model Gamos. As with the GRT-III, the GRT-4G trigger blade will help to greatly improve your accuracy in your late model Gamo.

What is the GRT-4G trigger blade made of

The GRT-4G trigger blade is Gold Anodized aircraft Aluminum and will adapt to all new late model Gamo's using the plastic trigger. It is designed to work only in the late Gamo's using the plastic trigger and will not fit anything else

Although the components of the GRT-4G trigger blade mod are not under heavy stress, their ability to hold a precision adjustment over a long period of time is critical to delivering the long term enhancement to accurate shooting that you paid for. It's for this reason that the GRT-4G trigger blade is CNC (Computer Numerically Controlled) machine manufactured from high grade aluminum alloy known for its strength. The blade is then anodized for wear and corrosion resistance

What does the GRT-4Gamo trigger blade do

The GRT-4G trigger blade changes the internal geometry as well as the ergonomics of the new Gamo trigger module using the plastic trigger and converts it from an allegedly 2-stage trigger to a true 2-stage trigger geometry while at the same time dramatically reducing the pull weight and still not compromise their new three point safety trigger.

NOTE: The latest production of the GRT-4G trigger blade no longer has a 1st stage adjustment screw. There are two reasons for this.

One is that the optimum 1st stage adjustment has now been machined and built into the trigger blade and two; it prevents accidentally compromising the safety.

But it's not just the improved trigger pull that makes the GRT-4G trigger so great. Just as important and maybe even more so, are ergonomics of the trigger. The ergonomic design change greatly enhances the trigger with a far more controlled trigger pull. It's what assists in making the big difference in the improvement of both accuracy and consistency.

There are a few out there that say that ergonomics doesn't matter.... but......, those that have experience with both the OEM trigger and the GRT-4G trigger blade know the difference and given the choice, will choose the GRT-4G trigger every time. It's a matter of what you expect for your money and with the GRT-4G trigger blade you get it all.
