Also pot metal is what you usually find used in metal toy cap pistols and replica, non firing model guns that are just used for display. If not cheaply plated, it usually has a dull finish and looks a bit like pewter metal, has little strength and breaks easily and wouldn't hold up to the chamber pressures used in a real firearm unless maybe just a .22 short single shot with a really thick barrel. I have a replica, non firing, dull, raw pewter like finish, Colt 1873 peacemaker that's made of pot metal, that I just use for bookcase display and practicing twirling.
