The mag that broke is the Kahr 7 rounder that came with the used Kahr K9 I picked up just as I joined this forum. It's a 1995 pistol.....who knows how many rounds?
Rear vertical part of follower broke off when I loaded it with 7 rounds the other night. Bored and loaded it up, broke off, had to disassemble to get it apart. The other two mags were Kahr 8 rounders, which were not in production in 1995 to my knowledge.
