This is for the ar pistol platform. The magazine Is not in the pistol grip, but in front of. The purpose Is to limit a pistol to a standard style and anything else needs to be a 16" barrel rifle. This part of the bill will outlaw ar pistols, ak pistols and all pcc that is classified as a pistol due to the short barrel.My thinking is, The capacity to accept a detachable ammunition feeding device at some location outside of the pistol grip could be interpreted to mean an extended magazine, and since there are companies that make extended mags for most popular pistols... I don't know what they mean, since I've never heard of what seems to say some kind of aluminum something. Does any mag manufacturer make mags from aluminum? All it might take is one. Anyone know what the bill refers to? It's the weirdest wording I ever saw. Mags attach at a point in the grip. Does any company make a spare tubular mag system for any pistol that is detachable? Perhaps there is to get around the standard box magazine standard. I never take it for granted there are intelligent anti-gun freaks that know something I don't. Leave to the 75 Soros-funded DAs to persecute and let you wait for years until it gets to the SC, which if Republicans lose the Senate, can go left.
