Gunpowder in guns burns independently of atmosphere. Guns will work in
space.


Absolutely not. The air in the cartridge is enough to start
combustion, and begin the expulsion of the slug, but a shot in space
would definitely be of lower muzzle velocity due to degraded burn
process.

Gunpowder doesn't burn in a oxygen free environment. There is air in
the cartridge. In space, I would want it to be there as well. Being
a vacuum, it would likely get removed as the cartridge may be
"airtight" at sea level in Earth's atmosphere, but certainly isn't
under a vacuum. It would get voided.
