This was a quick 3-stage USPSA match that I attended after getting off work yesterday. I was using my CZ Gen1 P-07 carry gun from concealment with off the shelf ammo. This gun has been plagued with trigger reset issues from the day I bought it (used), and the problem persisted at this match. The trigger is very slow to reset (intermittently) which causes delayed follow-up shots as well as accuracy issues due to timing of the trigger pull. I've been polishing and tinkering with the internals to resolve the issue, but I have still not figured out the problem. 😕
UPDATE: After spending several more hours troubleshooting the gun at home, I was finally able to replicate and determine the cause of the trigger reset issues. Apparently, the Gen1 frames were made from a slightly softer polymer than the Gen2 frames, and the strength of my grip flexes the frame just enough to bind up the trigger components causing a slow/sticky reset. I ended up replacing all of the Gen1 trigger components (including the hammer and trigger itself) to brand new Gen2 components that I stoned and polished. Replacing all the internal parts has completely eliminated the trigger reset issue and the double action trigger pull is now very smooth. My guess is that the newer parts have tolerances that work better together even when the frame flexes slightly when I grip the gun.
