I just recently purchased a used PM9. Once I got home, I noticed the magazine didn't fit flush and there was about an eight of an inch of play where the magazine could be pulled.
Just to make sure it wasnt the mag I tried it in my MK9 and the fit was perfect. All mags were off in the PM9.
Wanted to see if anyone else had this issue in the PM9 and some possible solutions to make the mags fit tighter. Thanks
