The Irish gun maker William Rigby made this 54 caliber flintlock pistol. It has a captive rammer system. The lock and hammer are lightly engraved. The mechanical function is very good and the sliding safety works correctly. The right side of the grip was either modified for the shooter or damaged. The barrel is 5 ½” and is 11 ¾” overall in length. Rigby guns have always been known for quality and reliable function.
