pump actions are reliable but don't care any less about atmosphere than automatic actions, gas-blowback or recoil operated firearms produce their own gasses/forces (from the bullet propellant) and contain their own oxidizers (no need for atmosphere)
basically just get a power armor suit with a full-auto multipurpose flechette/microgrenade launcher mounted to one of the arms or your shoulder.
What about different gravity would that cause guns to fail? Americans go to the moon and don't even test any guns smh my head
If a gun can fire upside down it can fire in a zero g environment.
What if there's more g's, enough g so the firing system can't eject the shell or go back far enough
If the g is so high that it can't eject, chances are you can't lift the gun anyway.
a pump shotgun no, but potentially some gas operated systems? i'm not really sure how gravity/vacuum would affect any recoil operating system like that.
pump action shotguns will still be used because they sound really cool
You watched that Forgotten Weapons video didn’t you.
I wonder what the Borg would do against buckshot? You'd think the Federation would stock some kinetic small and large arms for the odd species that shrugs off phaser blasts.
IDK, even pump shotguns would be subject to issues with vaccuum environments , but I guess differences in atmospheric pressure in alien environments might be an issue if it changes how fast the gas disperses.
