It would. Your example demonstrates that the second amendment does not apply to the states -- if it did, equal protection and due process would demand that the laws be uniform.
"Since they are not limited in what they may regulate (your notion) why haven't the folks at Commerce cracked-down on the lack of 'uniformity' in this regard?"
Well, the Commerce Clause gives Congres the power. It doesn't mean that Congress must exercise the power.
What is with this obsession they have for uniformity and centralization? They're pushing ideas that are the polar opposites of those stated by the Founding Fathers.
