I have owned my P3-AT for about 6 monthes now and had zero issues. I cleaned the gun and lubed it out of the box, I also checked out the F&B articles. It appeared that my HC P3-AT did not need any F&B, the machine marks and edges were much better than my buddies parkerized model, so I left it as is. I ran 250 rounds through it, Magtech, CCI, Remington ... cleaning it every 50 rounds and had no issues at all. Fast forward to yesterday at the range, every other round failed to fire. I had all 3 brands of ammo with me , so I know it is not a hard primer issue. I took the gun apart and checked the firing pin first, every thing was free and clean. I also cleaned the extractor and screw while I had it apart. I noticed 2 things when I had it apart, on the ejection port side and oposite the ejector the rail is dinged up pretty good. Also the front top egde of the magazine well directly under the feed ramp, is slightly dinged. I removed all sharp edges from these spots and filled the mag up. Same thing occured. I checked and found that all I have to do to get it to fire is nudge the slide rearward 1/8" and it will fire fine. I also looked at the end fo the rounds that failed to fire and noticed they each have a deep deformation in them. I can only assume that this mark is from them running in to the feed ramp, or the top edge of the chamber. I know that I am not limp wristing the gun, nor am I short stroking the trigger. What else could it be? I really like the gun, but now I wonder how reliable it is?
