After waiting months for a P-3AT, I finally found one. At the shop I noticed it was hard to rack. I have quite a few semi's (M&P, Beretta's, Bulgarian Mak, PM9...) , and this seemed to be the hardest. First thing I did was field strip it sand with 400 sandpaper, then buff it out with a dremel and Flitz polish just like the directions show. I oiled it up real good and it's still a bear to rack. Is this common with a new gun? A little piece fell out of the frame when I turned it upside down, but it looks like there's only one way to put it in. Any help appreciated!!!
