Today I went to the local gun range to shoot the p3at, at this point I have about 250 rounds thru the gun and have cleaned it after each use. Today I was expecting everything to go as always but after the first pull of the trigger nothing happened :-[, reracked it, second pull, nothing :'(. Switched ammo to something that has always worked, it fired but failed to eject the casing >. I went out to the show room and removed the slide, everything looked OK then I noticed that the famous little screw looked somewhat weird, but it was tight so back inside I went to try again, another fire but again it did not eject the casing.. I had a hunch that I knew where the problem was because the last time I shot and cleaned it I noticed the famous little screw was loose so I removed it cleaned the threads, added locktite and put it back. Next door is a gun smith so I went to him seeking advice, What we found was just as I thought, weeks before when I removed the famous screw somehow it got miss alligned and was causing problems with the firing pin and not holding tension on the extractor which we found in place but loose. The Smith worked the slide, hammer and trigger which allowed the famous screw to go in 2 additional complete turns, tightening the spring and extractor. he never disassembled the gun so I dont know the exact problem, Back to the range I went and it fired 50 + rounds with no problem. The scarry part is I have had the gun in my pocket for the last 2 weeks thinking it was ready to protect me or my family if needed. Tonight I plan on looking at the parts diagram to see what happened and Tomorrow I will clean it so I'll look further into how the screw should fit so not to duplicat that error again. Sorry for the long story Im just trying to share my mistake so hopefully no one else makes the same one.
