Not sure I agree with your interpretation of the 2nd amendment. Neither have the courts.
A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed
Well regulated = properly equipped
Militia = all freeborn men 18 to 60
Arms = the weapons used by said militia, that is, the weapons and tools of war
