Part 3/14:
On Earth, gravity and footed stance absorb the backward push when firing a gun. In space, however, firing a weapon would send the shooter flying backward, acting as a makeshift propulsion system. Astronauts have even carried weapons like the TKB-5P pistols for survival purposes, not combat, during re-entry in Siberia, showcasing the real-world applicability of firearms in vacuum.
In essence: Space guns would work, bullets would fly farther and faster, but shooters would be pushed backward with each shot—creating a surreal and chaotic combat scenario.
