To whit, our favorite whipping boy, gun control. Any and all gun bans are illegal. The "F" portion of the BATFE is entirely ILLEGAL. As are the California bans, NY bans, ect... While it could be argued that the Militia Clause could be used to "regulate" the wearing of arms, this cannot be used to contrue a denial of RKBA completely. As in Texas. You cannot carry pistols openly and CCW is strictly "regulated". This puts Texas at odds with the "shall not be infringed" and well outside any reasonable "regulation" of the militia. The "militia", you and I, were never to be "debarred the use of arms".
Best bet would be to get rid of all Federal gun laws and revamp all State laws on the Alaska model.
"This is basic Constitution 101"
It's also Federalist 39, one of the best and most instructive about what this country is.
