I'd protest having to put trigger locks on all the guns
... What are trigger locks??? Are they that locking device that you throw out when you get your revolver? I would think a gun would be pretty useless with one if needed in a hurry .... I guess you could throw the whole thing at the perpetrator like a baseball.... might work
Primer size depends on the cartridge. Simple as that.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
