Sticky trigger return
Well, the P-11 with a 40 S&W conversion that I recently acquired suddenly developed a trigger problem, it would not re-set after firing a round, I had to push the trigger forward just a little bit to get it to se-set. I checked out the usual suspects, trigger return spring, clean and polish the trigger bar, make sure the trigger spring is in the groove properly and lube the grip frame area, lube with grease in the appropriate areas, etc. Still no fix to the problem. So... taking it down again I watched what was happening as I move the trigger and noticed that it hesitated as the trigger pin moved into the grip frame area, it was at that location that all seemed to hang up. I gave a slight tappy-tappy to the trigger pin to move it down just a tad and all the problems disappeared! The pin was apparently producing just enough to drag on the grip frame and hold the trigger from moving forward after firing. Just something different from the usual "trigger spring out of the groove" response I usually see. Hope this may help someone in the future.
