I'm whelmed by your answer.Just because Guns and ammo or the Navy don't know a gun from a rifle doesn't mean everyone needs to be lax.Of course now days pistol mean semi auto and revolver is different on the old gun listings.I often questioned that as single shots and revolvers were pistoles long before the semi was invented.On ships folks call them guns but in truth they are artilary pieces on cannon. Its all kinda like Comic Book which ain't realy a book.
