Or maybe you've been lucky, kahrguy.
That would be my guess, since one of the more popular references out there for owners of polymer Kahrs is the "fluff and buff" guide. My PM9 required that, and ran noticeably better afterward, but it still preferred six round magazines over seven round magazines.
I know other Kahr owners who have had similar experiences.
That said, I know a few who have had better luck.
Most, from both camps, have other small guns, too, and can shoot them well enough.
I typically use Speer FMJ, CorBon DPX115, Speer Gold Dot 124, and in some guns HST 147 when shooting 9mm. Do you see some problem with my ammo, or are you faulting me as shooter?
