The TP-82 pistol (Russian: ТП-82) is a triple-barreled Soviet firearm that was carried by cosmonauts on space missions. It is intended as a survival aid to be used after landings and before recovery in the Siberian wilderness. The upper two smoothbore barrels use 12.5 mm caliber ammunition, and the lower rifled barrel uses 5.45 mm caliber ammunition. The pistol can be used for hunting, to defend against predators and for visual and auditory distress signals. The detachable buttstock is also a machete that comes with a canvas sheath.
