GRT III question about letting off trigger
« on: April 25, 2010, 11:48:15 AM »


This weekend I was shooting my Benji Trail XL that has a GRT III trigger, As I was lining up a shot I pulled the trigger through the first stage but then had to back out of the shot and not pull the trigger. I set the gun aside, then returned and started to line up my shot. I noticed the trigger now had a lot of free play in it as if there was no spring loading that returned it to an unfired state. Is this normal? If not, what might I possibly check? The trigger seemed to go in just fine and I have been shooting it OK for a couple weeks. I used light lubrication on the contact points between the GRT III and the trigger firing mechanism.





Thanks!

The trigger is fine you had just pulled through the first stage. The trigger doesn't have the spring tension that the stock trigger had, remember that spring that came out with the old trigger. Ed

Should I feel a pronounced first and second stage? I know the instructions talk about adjustments for these but so far I've pretty much noticed just a long but crisper trigger pull. No initial first stage followed by a short, crisp second stage. Sorta feels like my trigger breaks and fires the gun at the end of the first stage. I'm not sure. I swapped out that factory trigger so fast I didn't get a chance to really notice.

The trigger's come pre-adjusted but you can adjust it to get a more pronounced first stage. Bob has a section on his site that takes you through the adjustment's, troubleshooting etc.. The site is in our MALL section and follow the instruction's to a "T" and adjust in small increments. Ed

Per the instructions

Important Safety note regarding balked fires:

If you start to pull the trigger, but then release it without firing, the sear will not reset to its original (as-cocked) state automatically. This may leave your rifle on the verge of firing and therefore in an unsafe condition where the slightest jolt or vibration might cause a misfire. Therefore, if you begin to take a shot, but then change your mind after having already started to pull the trigger, it is important to always re-cock the gun to reset the sear.

The non-resetting sear is not a side effect of the GRT-III trigger blade modification but  you probably never noticed it before only because the blade return spring of the unmodified trigger creates the illusion of automatic reset when the trigger blade is released. A partial pull-through has always had this potential for leaving the sear in a state of partial disengagement.  Always re-cock a gun whenever a trigger is even touched without actual firing on any gun.

Hello Wahoowad. About that trigger. It might be possible that your trigger needs a little bit of adjustment but it sounds like you're not too far off. Follow the instructions and adjust in small increments. What I expect on that trigger(I have 3) is just what you're probably looking for. That 1st stage is essentially the take up of the slack. At the end of it's travel you should feel a slight resistance. The next breath of pressure will trip the sear.The 2nd stage, if you want to call it that, is the break or the sear release and the gun fires. Spend a little time (it's fun) tinkering with it when you shoot and you'll probably really learn to appreciate what a great trigger upgrade it is. A few years ago, CharlieDaTuna himself installed and adjusted the GRT trigger in a gun he tuned for me that had a 10lb trigger and a mile of take up when I sent it to him. When I got the rifle back the gold trigger was a true transformation. Shorter take up with a distinct"click" that you can feel at the end of the take up. A couple of ounces of pressure is all it takes at the end of the 1st stage take up.
