Oh, one more thing, buy different ammo. My Kahrr (sp?) will only fire certain ammo. Some 9mm is 1”1/16 and some is 1”3/16. My gun will only fire the former.
A cartridge diameter difference of 1/8th inch?!?! That’s a BIG difference for a cartridge let alone the actual bullet. You sure you don’t mean 1/32nd or 1/16th inch?
