California is in the process of doing the same (defining semi-auto 22s as “assault weapons”, doesn’t even need to have a pistol grip). There is also a bill that bans mere posession of a magazine > 10 rounds.

If these can’t eventually be overturned on the basis of Heller/McDonald, then the 2A is dead because Heller/McDonald would be meaningless.

You can thank Justice Scalia for his ruling in Heller that allowed for “Reasonable Restrictions” on the Second Amendment.
I don't think the Heller case would help fight the Connecticut law. On the contrary, I think it could be used to justify “Reasonable Restrictions” by the Connecticut Legislature.

I personally think the Connecticut law is BS and unconstitutional.
