The SAC-46 (aka: Flying Dragon and "Gun, Dart, Carbon Dioxide Propelled") is an American clandestine handgun from 1945 which was developed for the Office of Strategic Services (OSS), a predecessor to the Central Intelligence Agency (CIA).
One of their ideas in 1943 was the SAC-46 pistol, which was intended to fire a special designed poisoned dart propelled by a commercial type CO2-cartridge like an air gun.
[2] Due to her specialized applications and large size the gun is normally transported disassembled and is assembled and loaded just prior to the shooting.
[2] In February 1945 operational examples of the SAC-46 were requested for an actual OSS mission and a first batch of six guns was manufactured in April 1945 by the Long Engineering and Research Company.
[2] Until the end of World War II no use of the SAC-46 in an actual mission was documented and at this point the OSS had still 12 of the guns and 1,011 darts in its inventory.
[2] A surviving example of the SAC-46 is on display in the John F. Kennedy Special Warfare Museum in Fort Bragg.
