Once upon a time during WWII a lethal dart gun code name “Bigot” was created to be used by commandos to covertly eliminate sentries, this dart gun was constructed from a M1911 .45 caliber pistol. The Office of Strategic Services predecessors of the CIA developed this clandestine weapon, its unknown as to what advantage this has over a silenced pistol. The weapon never made it out of the research and development department, but this didn't stop Ian McCollum from Forgotten Weapons to get his hands on one to check out, see the video and Ian's observation.
