A friend has a FNP 45 tactical pistol. We were putting some rounds through it Sunday or at least trying to. Seemed to me like every other shot or so I had to rack the slide because it failed to feed another round. At first I thought it was just the black Hills jhp but it did it will various ball as well...all 230gr. I've quite a few different reports online of similar issues, not to mention a few that blew up due to insufficient chamber support but that's another story. I'm thinking it could be a magazine issue, he has 4 and although we didn't really pay attention if it was certain ones it happened with more than just one of them. Any thoughts?
