Gunpowder is self oxidizing. As long as they used a non-evaporating lubricant on the actual mechanical components like graphite, and included a barrel liquid cooling loop, the M2 would operate totally fine in space.
That’s why I say you need to provide a closed liquid coolant loop around the barrel that would ve integrated with your ship’s heat management system, to replace the air cooling of the barrel.
