That's the problem with nitpicking around the edges of these issues instead of addressing the constitutional issue; you end up with a bunch of inconstant local laws and constant court challenges.

It's silly to equate "a well regulated militia" with what type of gun bubba gets to use to hunt deer. The second amendment was written at a time when the only military in the nation was formed from local militias who showed up with their own weapons. If you wanted to actually meet the intent of the second amendment in the 21st century, you would have to own aircraft carriers.
