Derringer

A derringer is a teeny-tiny gun that fits in the palm of your hand. It has only two barrels, which means it can shoot two bullets at a time. Derringers were very popular a long time ago, back when cowboys and outlaws were roaming around the wild west. People would use derringers for protection because they were easy to carry and conceal. Nowadays, derringers are mostly used for fun or as collector's items. They may be small, but they can still be very dangerous if not handled properly, so it's all about safety first!
