I'm a new member and a new owner. Thought I'd share my first experiences with this tiny gun. BTW: mine too has that tiny hole in the slide but it looks as if many owners are reporting that little hole so I'll wait to see how this develops. The gun is the new, SG, P-3AT that was given some F&B by the gunsmith who sold me the gun. He had about 5 for sale at the show. All were SG models. His F&B consists of his version of the ramp mod, deburring and polishing other parts "as necessary", black baked-on Gun-Kote treatment on the slide, and a couple of little dots of sight paint. He also test fires a few clips of ammo to see that it feeds reliably. First thing I did was disassemble the gun and then I completed a full inspection, cleaning, and lubrication. At the range I fired a box of 50 Silvertips with no FTF or FTE. That was encouraging. Not one failure. Next I fired a box of 20 Hyrda-Shok and again, not one FTF or FTE. Next I fired some range re-load FMJ. I noticed the slide was reluctant to chamber the first round. Twice the first round did not chamber until I nudged the slide forward, and twice it chambered but sluggishly. I could tell the slide was hesitating as the new round began its trip up the ramp (tiny smileys too). In these 4 cases it was only with the range re-load FMJ ammo. The gun fired, extracted, and ejected every one of the range re-loaded shells. And finally, I fired a box of 20 Hydra-Shok with no FTF or FTE. So it appears that the ramp needs shortening. All in all the gun was 100% reliable with factory ammo. It's fun to shoot, the recoil is mild compared to my Wilson 45 and other larger handguns I've fired. I could shoot it all day... Accuracy? Well, it's going to take some practice to get good at point-shooting with this tiny gun. In a pressure situation I had better be close to the target. Smileys? Yes, but just a hint and with the range re-load junk. I never fired any factory FMJ. In my opinion (when tuned up)... this is a pretty good pocket gun as long as you use good factory ammunition. It seems solid and well built. I was surprised such a little pistol could be so nice.
