Each state has an enormous amount of power over the possession and use of firearms and other weapons; the 2nd Amendment left that power to the states.
A state can require that all weapons that the state classifies as suitable for military use, be stored in state armories that are typically scattered across a state, county by county.
It won’t surprise, to see some states now pass legislation requiring such storage.
One plus side of that, is that the armories become the honeypot for the Crown’s (currently the leftist dictatorship in waiting of Obama’s) ambitions; and as a honeypot, should the nationalizing forces of the left, move against the armories, then the people will know that the established threshold has been crossed.
As it was first in 1774 during the Powder Alarm.
So, you get to keep a “personal sidearm” and your hunting rifle and shotgun, but the rest of your “toys” are stored at the armory.
The NRA would probably campaign to have some part in that development.
This is just a possibility; but I have been expecting it for some time - I suspect it is more a probability now.
In addition to, some legislatures requiring a return to militia assembly and training, in order to re-establish what was once relatively common practice.

“I like the idea of gun safes in multiple locations. Much better than disarming all law abiding US citizens.”
