[Final Fantasy VII] Barret: Is it possible to properly maintain a gun using only one hand?

(I'm hoping to catch the attention of some gun owners here)

So all of the maintenance of a fully automatic firearm that Barret has on his wrist (cleaning, oiling, reloading, other things I'm unaware of); could he feasibly be able to take care of all of that with his one good hand, or would he require some assistance from someone else?

I always assumed there was some magic involved in most if not all gun use and maintenance. AKA how Barrit’s arm or Vincent’s rifle have infinite bullets despite having no place for a belt feed or large magazine. So the bullets are magically generated, and upkeep might be a combination of mundane repare and built-in enchantments. 

The same logic applied to most of the odd technology in FF7 - how the huge WEAPONs operated, how most of the Shinra mecha enemies functioned, how the Highwind stayed airborne. Magic wasn’t just the use of Mako or Materia, it was inherent throughout Gaia and infused itself in everyday life.
