GTX II = double set trigger--
« on: September 22, 2006, 05:14:00 PM »
I hesitated about posting this, mostly because the ease of slipping over the edge to unsafe is definitely here.  And this one could be a fluke, since I haven't heard of this anywhere else, that seems possible.  But here goes.  Bob, I definitely need your input here.

I installed my old GTX II trigger into a friends Varmint Stalker/S1K.  I thought I'd tested it to make sure everything was working properly, especially the safety, but I did have it set to a VERY light pull.  Well, the friend called the other night to tell me the rifle fired even with the safety set.  To any of you familiar with these triggers, it's obvious I had the 2nd stage turned in way too far.  Well, I got the gun back, and started adjusting the 2nd stage back out.  My shooting procedure is unvarying, as soon as I finish my follow through, I set the safety.  I'd back off the screw, cock and load, then try to pull the trigger with the safety on.  After a couple of adjustments, it stopped shooting through the safety.  But the trigger was still nice and light.  Almost too light.  Then I tried it, but without pulling the trigger with the safety on.  REALLY heavy!  Then I realized what was happening, and what the procedure needed to be.  Safety on, cock and load, pull trigger WITH THE SAFETY STILL ON, safety off, fire.  I don't have a trigger guage, but the pull has to measure in ounces this way.  In short, this thing set up this way behaves like a double set trigger.

Okay, before you all start jumping all over me, I KNOW that this is well outside the normal (AND SAFE!) adjustment range of the GTX trigger.  I assume it's pretty much the same for the GRT as well.  But I have backed the 2nd stage off enough that the safety works consistently.  At least for now.  I thought I had it there before I gave it back to my friend, but I seem to remember some later adjustments without checking the safety's operation.  So I either crossed the line later, or the adjustment shifted.  BTW, I did back it off even more from the point where it  stopped shooting through the safety.  Either way, once you get used to it, it's pretty cool.  And as long as the adjustment doesn't shift, it should be safe enough.  But that doesn't change the fact that this adjustment is way beyond anything recommended by Bob.  So proceed at your own risk.  Okay, Bob, now you can jump in and beat me about the head and shoulders with a busted rifle stock :-).  Later, people.

Okay, Bob, now you can jump in and beat me about the head and shoulders with a busted rifle stock!!!! Nope Dave....ain't gonna do it....lol...

But....

There has been a signicant change in the GRT-III trigger blade over the GTX-II trigger blade and even the GTX-III trigger blade. The nose of the trigger blade has been changed both in length as well as the depth and contour that makes the safety more positive. How the first stage is adjusted plays a big part in how the safety performs.

 The first stage in the GTX-II and GTX-III should be adjusted to a point where there is very little freeplay in the trigger, almost nil. As you go beyond that point, the less positive hold the safety has on the safety switch while at the same time,  shortening  the first stage travel to the second stage contact even to a point that it can overcome the second stage and revert it to s single stage trigger. Keep in mind that you may be forsaking the safety of the trigger by doing it.

And yes, you can adjust the trigger first and second stage down to a hair trigger and to a point that it can misfire. For that to happen, you must take it far beyond the normal adjustment range. For most shooter's, I strongly.... let me repeat.... strongly.... recommend that this not be done. It can make the gun dangerous.

That fact is, that the GRT-III trigger can be adjusted to however the shooter likes and is comfortable with but before it is shipped by me, I pre-adjust every GRT-III trigger blade in a Gamo trigger group so as to be both safe and at the same time effective as well as efficient and will accomodate most shooters needs.
