I recieved a Derringer .22 lr pistol shortly after my mother passed away. it is an over and under double barrel. it looks like it is in great shape but only the bottom barrel will fire. i took a closer look and noticed the hammer does not hit the upper fireing pin. does anyone have info on where to purchase new parts for this gun? any help will be greatly appreciated.
