Bought a new PM9 sat at the gun show. Was excited about breaking it in and making it my carry gun. 2nd magazine into breaking it in, the gun failed to eject, had to drop the magazine, pull the slide back, and push the casing out the bottom. That happened about 4 times, and then after round 30, the rest of the 170 rounds shot fine. Was using WWB and PMC. Yes i load by locking the slide back to chamber the rounds, and yes i cleaned it per the instruction manual. Today i picked up some wolf 9mm FMJ, and figured i would test the reliability after the 200 round break in... More Failure to Eject, about 5 more times, for my box of 50. Same issue, recoil spring stuck between the recoil spring guide and the front of the slide. Upon inspection, the recoil spring came out the front of the recoil spring guile, and the slide would not not go fully to the rear. I have some pictures i took with my blackberry, but they are blurry. So I will call Kahr tomorrow and probably have to send it in. Needless to say, i want to love this pistol, but its not earning my reliable stamp.
