I just acquired a second hand P320 which has not been upgraded yet. I don't know the round count but am guessing about 500. I took it out this afternoon and put a magazine through it.

The trigger press feels the same as every other 320 I've fired. The reset is different. Every other 320 has a audible click and you can feel when the trigger resets. This one resets at the same point but there is no click and I can't feel it reset. I have not detail stripped it yet.

Has anyone encountered this before and/ or know what may be causing it.

Thanks!

I detail stripped the pistol this evening, located the problem and corrected it. The pistol now functions properly.

The issue- the previous owner detail stripped the pistol to clean it. When he reassembled the pistol, he bent the trigger bar spring. I replaced it and no more problem.
