Because they are already in the pipeline, as someone else noted, I'm thinking mag restrictions, semi-auto bans.............anything that might be construed as "being in common usage".
CA, NY, MA, CT etc come to mind.
Eventually we can hope for national reciprocity for carry, both concealed and open. Maybe it might even go all the way to Constitutional carry.
Hopefully, the silly CA ban on mail ordering ammo will get overturned by a court somewhere also.
