I cleaned my P3AT this morning, and decided to clean the firing pin channel as well, for the first time I have owned the pistol. I backed out the firing pin screw with an allen wrench. It appeared to have lock tite or something equivalent on it. I then removed the firing pin and firing pin spring. I cleaned the channel, firing pin, and spring. ' When I reassemble this i have 3 questions: First, the small cut out on the firing pin goes up right? Second, if I tighten the firing pin screw up too much (ie, until all loose play is tightened up out of the screw), it appears to lock the firing pin in place and prevent it from moving. How do you know when you have the firing pin screw tightened up enough? Third, should I put some fresh lock tite on the firing pin screw since it seems to have come that way from the factory? Thanks in advance for the help!
