I finally managed to get a box of 380 (swapped a box of 40S&W for it) and got to shoot my P3AT. I really enjoyed shooting it; I just wish I could find where the brass got sent. I loaded up my first magazine with 5 rounds, and inserted it into the pistol. I gave it a quick tug only to have it pop out. So, I put it back in and tapped it with the heel of my palm. It again popped out. I put it back in with some 'authority' and it stayed until the first shot was fired. It then popped out. I'm thinking that this is most unsatisfactory, and that I must be doing something not quite correct. I did some fiddling, and found that if I pushed up on the mag base and in on the catch from the right side that it would make a nice click sound and stay put. I've done a search here to see if this has been a noted problem, but haven't found reference to it in regard to P3Ats. So, has anyone else experienced this? And will it cure itself or go away on its own? Or is there ought I should be doing to remedy the situation? Thanks for all input.
