Which means the Government could stipulate all firearm owners be required to use a certain gun which operates according to regulations and they show proper proficiency to use said gun.

Not playing lawyer, but there are gun-regulation cases out there that follow a different chain of thought. Sawed-off shotguns were not protected because they were not enough like standardized military weapons. I’m letting someone more familiar with the law dig that case out.
