Well, lets look at something fun, that none of us will ever be able to own, (and now that I know it exists, I really, really, want one) the TP-82 (TOZ-82), triple barrel survival pistol. 2x40gauge side by side, (I've also read 32 gauge) with a 5.45x39 under. The removable buttstock could also serve as a machete when unsheathed. Just the thing for when your capsule lands in the Siberian outback and it takes a day or two for the recovery crew to find you.

The TP-82 (Russian: ТП-82) was a triple-barrelled Soviet pistol that was carried by cosmonauts on space missions.
It was intended as a survival aid to be used after landings and before recovery in the Siberian wilderness. The TP-82 was the result of cosmonaut Alexy Leonov's concerns after being stranded in the Siberian wilderness when his Voskhod capsule malfunctioned. He was concerned that the 9-millimetre pistol that was provided in the survival kit would be ineffective against the Siberian wildlife, namely bears and wolves.[1]
The upper two smoothbore barrels used 12.5×70 mm ammunition (40 gauge), and the lower rifled barrel used 5.45×39mm ammunition. The pistol could be used for hunting, to defend against predators and for visible and audible distress signals. The detachable buttstock was also a machete that came with a canvas sheath.
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). In 2007,[2] 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.
