It was purportedly (and probably in actuality) intended as a survival aid to be used after landings and before recovery in the Siberian wilderness, although allegedly was intended as a defensive weapon against in-space attacks by the US space program.
Heat dissipation is an issue since there’s no air around to cool the barrel, although for this three shot weapon (two shotgun one rifle) it wouldn’t be a problem. This gun is mostly to fend off bears when you land in Siberia.
You are half right. The gun definitely is for bears, but, and get this, space bears
Normal or cocaine…space…bears?
Miniature giant space bears.
