I recently purchased a flat trigger from 10-8 performance. But I couldn't get the set screw to adjust. I heated it up and was able to loosen it making it protrude further out but t would only tighten a little. At its tightest point it wouldn't engage the disconnect properly to capture the hammer in the cocked position. I decided to take a dremel to it and grind off what I didn't want. The trigger face is solid so you cant adjust the trigger with the gun assembled. It seems to work (dry fire testing, I'll take t out soon to try it live). But since I haven't tested it out yet I put the original trigger back in. Anyone else have any similar experience with a new trigger.
