That's not exactly correct:
The act bans shipment, transport, ownership and use of guns or ammunition by individuals convicted of misdemeanor domestic violence, or who are under a restraining (protection) order for domestic abuse. [1]
Logically, then I think that the latter part (about the domestic restraining order provision) ought to be vulnerable now. However, I really doubt that Court would be willing to reexamine this in the current context, since in Emerson it was judged Constitutional. [2]
