Why not? I love my 30 carbine Ruger Blackhawk revolver, and I'd love to have one of the old AMT Automag III semi auto .30 carbine pistols. They are 100+ yard handguns.
Some people DO complain that they are too loud, but that doesn't bother me, and my reloads are much quieter than factory mil spec ammo, with the same performance.
I has a kick, but so does the .357 magnum
I was sitting two people over from a guy who intentionally shot an AMT long slide in 30 carbine inside a building. I don’t remember actually hearing it, the muzzle flash blinded me in the eye I didn’t get quite closed in time.
Startled doesn’t accurately describe everyone who wasn’t aware of what was going on until he lit that hardballer off.
