Law District of Columbia v Heller 554 US 570 2008 Question

I’m working on a law question and need an explanation to help me study.

District of Columbia v. Heller, 554 U.S. 570 (2008), is a landmark case

in which the Supreme Court of the United States held that the Second

Amendment protects an individual’s right to keep and bear arms,

unconnected with service in a militia, for traditionally lawful

purposes, such as self-defense within the home, but it did not hold that

this right cannot be regulated. With the concept of Federalism in

mind, discuss the following:

1) would it be Constitutional for a state to restrict gun ownership for private citizens to one single shot .22 rifle?

2) would it be Constitutional for a state to limit semi-automatic handgun magazine capacities to 3 bullets?

3) would it be Constitutional for the Federal Government make it illegal

for a private citizen to transport a semi-automatic handgun with a

magazine capacity of 3 bullets across state lines?
