False, as always.
As 5th Circuit Judge Robert M. Parker pointed out in his concurring opinion in United States v. Emerson, "The determination whether the rights bestowed by the Second Amendment are collective or individual is entirely unnecessary to resolve this case and has no bearing on the judgment we dictate by this opinion."
Your own utter failure to produce even a single case or authority holding that state or local regulation is violative of the 2nd Amendment demonstrates the poverty of your argument.
Or are you still having trouble with the words "supreme Law of the Land" and "shall not be infringed"? Here, go back and refamiliarize yourself...
