Soviet Cosmonaut Space Gun: Triple-barreled TP-82 pistol
TP-82s were carried regularly on Soviet and Russian space missions from 1986 to 2006. They were part of the Soyuz Portable Emergency-Survival Kit (Носимый аварийный запас, Nosimyi Avariynyi Zapas, NAZ).
It is intended as a survival aid to be used after landings and before recovery in the Siberian wilderness. It wasn’t just any gun, but “a deluxe all-in-one weapon with three barrels and a folding stock that doubles as a shovel and contains a swing-out machete,” according to space historian James Oberg.
In 2007, the media reported that the remaining ammunition for the TP-82 had become unusable and that a regular semi-automatic pistol would be used on future missions.
