The Cold War Cigarette Gun was made to be compact for concealment and yet labeled with popular brands to be carried in the open, usually in a breast pocket of a jacket. To use in a desperate situation the agent simply held the cig with his fingers and asked for a light. The tobacco end plug COULD be lit for a few seconds but the user usually had to either use his other fingers or teeth to pull the filter back enough to break the tether inside to the 5.7mm round located behind the tobacco plug. At sufficient pressure the tether broke and ignited the round which fired at 759 fps and had ME of 51 ft/lbs. At close range (2-5 ft) this was devastating. Most enemy agents were shot in the face and others in the chest when the cig was aimed. Loaded weigh was .018 kg and the round was 2.6 grams. Ammo was special 5.7x17mm RNL. Effective range was 1-2 meters, with 10 meters max. Hit probability at 1-2 meters was 99% but fell off after that. At 10 meters it was down to 37% or less. Female CIA Agents were issued lipstick guns in addition to the cig guns which were sometimes called “Nictorex Brand” which cost $22 each to make! The CIA also used modified old OSS-type MAC-Stingers that cost $45 each! The weirdest kill gun was the CIA multi-barrel “Ice Gun” which pneumatically fired cold ice rounds that penetrated the flesh and then melted away. No kidding!
