One shot was *not* enough to run off a mob in my experience back in LA in 1992.
I don’t have your experience. I would rather have a 6-shot revolver than a 2x4, all things being equal. It is almost impossible for Joe Blow to get a gun in NYC. I am just saying, if an old Colt Navy blackpowder revolver clone is legal in NYC, then I would get one and at least have something that is preferable to hand-to-hand combat.
