shot my PMR 30 for the first time yesterday. Btw. loading the magazine is a real bear! After the third shot the pistol jammed and I had to lock back the slide, remove the magazine to remove the cartridge. During the course of shooting 30 rounds it jammed a total of three times. I used Hornady Critical Defense, 45 Gr FTX. I will use several different cartridges the next time and give you an update.
