I just picked up a second hand P3AT to be a backup to my daily carry P3AT. This new gun appears unfired, but has a much looser slide to frame fit than my first one. If you lift up on the muzzle end of the slide, it lifts away just slightly from the frame. My first one does not exhibit this tendency. I will have to test fire the pistol shortly, but until then I am wondering if anyone else has noticed this condition.
