I have a PM9 that does the same thing. I bought it new and now have 300 + rounds through it, still have the problem. The ones I can't eject are the FMJ rounds. Any HP ejects fine. To clear the FMJ I had to drop the magazine, pull the slide back and poke the round out down through the handle. I also asked about it on here and got the standard answer about the break-in period which didn't really help. What I decided was that since it ejects the HPs fine (my self defense rounds anyway) that I was OK with the problem with round nose FMJs since I only target shoot with them. Other that this single problem, I love my PM9 and it is my primary carry piece. Good luck with yours!
