I receved a new in the box P3AT this past weekend as a belated christmas present. So far so good. I imagaine it will make a nice CCW. I took it to the range and put 30 rounds through it with no problems, picked up a spare mag for it at the gun store and cleaned it. However When I loaded it today, I loaded the mag, inserted it into the gun, racked the slide to chamber a round and the first round jammed in the breech. I pulled back on the slide several more times and it chambered. It did this several times. Any thoughts on this?
