Except for the first two centuries after that was written the Supreme Court didn't interpret that section to mean anything goes. In particular, in 1939 it upheld a federal ban on sawed-off shotguns (United States v. Miller). It was not until 2008 when in District of Columbia v. Heller they said the Second Amendment protects an individual right to possess a firearm unconnected with service in a militia. So it's not so clean cut as you'd think.
