For your consideration is a Hopkins & Allen XL single shot derringer pistol. This single shot pistol is chambered in .41 RF. The 2 ½” barrel is marked on the top "XL Derringer” and “Pat. Apr 5. 1870”. The firearm utilizes a fixed blade front sight, spur trigger and checkered hammer. The rosewood bird head grips are in good condition. To load, the hammer is brought back to half-cock, the barrel release button on the bottom of the frame is pressed and the barrel will then pivot exposing the breech for loading a single cartridge. Once loaded, the barrel is swung back into battery, the hammer pulled to full-cock and the trigger pulled to fire the weapon. The nickel finish on the barrel shows a nice patina. Serial Number: 16. This firearm qualifies as an Antique, and does not require FFL Transfer or NICS Background Check.
