Hi Everyone,
I have an all original STI Eagle 5" with a bushing. Original except I sent it back to STI recently to fix a broken barrel lug (timing was off). I suspect this might or might not have anything to do with my issue now but it is odd having not done this prior. They machined the frame slightly and went from a #2 to a #3 lug. If you do a timing check it still fails so I imagine its still off slightly. Pistol has about 5K rounds through it prior and about 1K after and was running like a champ up until last months match. Trigger is around 2.8Lbs.
Example, I will be shooting a string of targets and maybe 1 trigger pull out of the batch will be much harder to pull than the others so I nose dive it. Totally random and unpredictable. Last match it did this twice in 7 stages. I broke the pistol down, cleaned and checked everything. I have kept a round count vs occurrence since and it seems so far to be three times in 140 rounds, totally random. I even backed out the trigger screw a little but it didn't make a difference in my last practice. Its loctited in place so I'm not sure how that could be the issue anyway as it can't move.
The issue causes misses and lost time in a match so its a little frustrating.
Any ideas?
