Hello KTOG, I just want to start off by saying that this community is an amazing resource! This is my first post (apologies, because it'll probably be a long one...), but I've been lurking around and reading since before i purchased a new P3AT a few weeks ago. I've been googling non-stop to try to find a solution, and when just about every search led me to this forum, I began using the forum's search function to try to find a fix for the issue (if it is an issue at all, that is), in hope that I could fix myself, without having to make the classic (and redundant) "HELP!!!" noob post for a solution that has already been explained. Since I started this topic, it's clear i was not successful. Please forgive if this question has already been answered and I happened to miss it somehow. Thanks. So... When I first purchased this piece I was a little surprised (yet thrilled), that it performed flawlessly right out of the box. Took it out to the range for a break in, not one malfunction of any kind in 200 rounds. In fact, the gun has still had no malf of any kind besides one FTF, which i'm positive was due to limpwristing. So, a friend of mine was so impressed with my new piece that he decided to pick one up too. He had problems from the word "go". Failures to feed, failures to fire, light strikes, and a weird clicking sound at the end of the trigger pull, that coincided with the hammer not falling properly. When we took it apart to check it out, we noticed that the hammer block was snagging on a roll pin in the hammer that appeared to be improperly oriented. After the roll pin was repositioned the clicking at the end of the trigger pull ceased and the hammer began dropping properly and reliably (i noticed afterwards while searching that two members of this board in Montana had what sounds like the same problem with the roll pin). A FnB took care of the feeding issues and cutting a couple coils off the firing pin spring (i've read varied opinions on this, but for the problem i've got it's inconsequential) resolved the light strikes. His P3AT now seems to function flawlessly. Now, the only slight problem i had was that when firing HP's, unless i racked the slide very aggressively, the slide would not come forward and chamber the round. After observing how smoothly my friend's gun fed HP's after the polishing of the feed ramp during the FnB, I decided to do the same. I suppose I should have left well enough alone, but I figured since I already had the piece disassembled, I ought to go ahead and do a thorough FnB. I polished the feed ramp, outside of the barrel, slide rails, sides (but not the groove) and the inside of the cut out of the trigger bar, all with 1000 - 1500 grit polishing cloths. At the end, everything looked great and felt smooth. I also took some 600 grit sandpaper and removed some of the excess plastic around the trigger well and all the way around the inside of the trigger guard. Also smoothed out the seam on the front of the trigger, at the end everything felt and looked great. THE PROBLEM: When I put the piece back together, i now have a click at the end of my trigger pull when the hammer is down. Even though the gun seems to function normally, and it doesn't appear to effect the operation of the hammer (as it did on my friend's gun), I still find it troublesome that it is clicking now, when it never did before, and for the life of me i cant come up with a good explanation or fix for it. I've checked the orientation of the roll pin and it isn't that, however just to be on the safe side and completely eliminate it as a factor, i repositioned it. It does not click if the hammer is all the way down and the slide is off, however, if i manually cock the hammer and let it fall, but not all the way (about to the position it would be in if the slide were on, I can make it make the clicking sound and observe the hammer block moving slightly forward and then falling back onto the hammer pin ( the source of the clicking as far as i can tell). Also, it appears to never make the click on the trigger pull that actually drops the cocked hammer. It only begins to click on subsequent pulls of the trigger. Any ideas on why it's clicking now and not before, if it's normal or not, and how to make it quit doing it, would be much appreciated. I've taken it apart about twenty times now, no exaggeration. No success. I'm pulling my hair out. HELP!!!
