SWD M11A1 .380. This is the gun that can take a 9MM conversion upper available from Lage Manufacturing. Lage also has excellent shoulder stocks to complete the gun. This one was used in the movie industry (documentation included with the gun) and has never been fired with live ammo. The muzzle is threaded for a bank-fire device. The barrel can be fired with real ammo by unscrewing the hidden adapter The finish is worn from use in films but the gun is mechanically excellent. I will refinish it if you like or leave as is with its colorful history.
