JNW Posted November 27, 2019 Share Posted November 27, 2019 I just shot my relatively new (several months old) TSO 9mm and had my first problem. I’ve got about 2,000 rounds of factory 124 grain ammo through it and was shooting American Eagle today. All of a sudden while shooting I had a dead trigger. The gun had fired, ejected, cocked the hammer and loaded a new round. However, the trigger had not reset. It did this several times and then started doing it every time. It even did it with a fresh mag in and I racked the slide by hand all the way back. Found that the hammer was not quite cocked all the way back. If I pushed down on the hammer a small amount it would cock and reset the trigger. It now fails every time. Is it just some debris in it or is something really wrong?

George16 Posted November 27, 2019 Share Posted November 27, 2019 First thing, have you checked the overtravel screw? Remove it for now and try shooting it again to see if it works. If it does, just adjust your overtravel screwto allow it to reset. If not, open it up and check/clean to see what’s going on inside? Link to comment Share on other sites More sharing options...
adamge Posted November 27, 2019 Share Posted November 27, 2019 I would recommend checking, and backing out, the over-travel and over-reset set screws in the trigger shoe. Link to comment Share on other sites More sharing options...
eerw Posted November 28, 2019 Share Posted November 28, 2019 ^^^ check pretravel and overtravel adjustment screws about the only thing that will mess you up. Link to comment Share on other sites More sharing options...
igolfat8 Posted November 28, 2019 Share Posted November 28, 2019 Have you verified that the trigger return spring isn’t broken? Link to comment Share on other sites More sharing options...
JNW Posted November 28, 2019 Author Share Posted November 28, 2019 Thanks! I wanted to ask on this forum before I did any thing. I’ve got a frame mounted optic so this is my opportunity to remove the rear site so I can remove the slide easily. Jeff Link to comment Share on other sites More sharing options...
mveto Posted November 28, 2019 Share Posted November 28, 2019 I had the same issue with my TS when I first got it, somehow the pre travel screw started to back out and wouldn’t allow the trigger to reset fully. Just had to screw it back in a little and got it back to normal. Link to comment Share on other sites More sharing options...
GrumpyOne Posted November 28, 2019 Share Posted November 28, 2019 Heard that the issue was with the aluminum trigger. It was said that the over travel screw would retain its position better with the polymer trigger than with the aluminum trigger. I have the aluminum trigger, but haven't seen any movement of the screw. Link to comment Share on other sites More sharing options...

I actually swapped it out for the aluminum trigger and had to lock tight both screws in place. I like the feel of the aluminum much better than the stock plastic trigger.

JNW Posted December 8, 2019 Author Share Posted December 8, 2019 Finally got a chance to work on my pistol. I backed the pretravel screw out 1/4 turn and it worked, but I gave it about 1/3 more. I initially had it set up right on the edge of functionality. It now has a bit more pretravel than I like, but it should shoot just fine. Also took off the rear sight to make this easier in the future. Man, was that thing on tight! Thanks again for all the help! Jeff Link to comment Share on other sites More sharing options...
