Pen guns have been used all over the world throughout the 20th Century by intelligence agencies, covert operators, assassins, and even regular citizens interested in self defense. Pen guns are single-shot weapons, often in a small caliber such as .22 rimfire, which appear to be a regular inkpen at first glance.
Pen guns are simplistic, easily manufactured, and can take on a variety of appearances. The Office of Strategic Services issued a pen gun known as the Stinger during World War II, and the Central Intelligence Agency later created an updated version which looked more like a pocket flashlight, firing a 9mm Parabellum cartridge.
Other similar disguised weapons include lipstick guns, such as the one on display at the International Spy Museum, flashlight guns, and even cigarette pistols.
