If your proposal doesn't appeal to the 35 states who support permitless open carry you're not likely to see any of this improve in our lifetimes (
Soon to be 36 states, once Florida passes their permitless open carry bill).
If we actually want to make progress keeping guns out of the hands of dangerous people we'll need to try and tackle it without impacting law abiding citizens. Otherwise it's a non-starter in at least 35 states (soon 36) and will be doomed to fail.
So if it makes buying guns harder for law abiding citizens, or puts them on a list, or in any way inconveniences them... It'll go nowhere.
There are solutions that don't do any of that, and that nearly all law abiding citizens would support. The fact that there is nobody trying to do any of that exposes this whole thing as playing politics. Nobody who matters actually cares about real solutions for this. Or if they are one of the few who actually do care, they don't know enough about it to do anything logical.
Again, that would be 36 out of 50 states allowing permitless open carry. Up from 28 out of 50 only a few years ago.
We need to get realistic about how to address violent crime. The current "anti gun" movement is having the opposite impact.
More people are buying guns now than ever before. More women. More minorities. It is now easier to make a gun than ever before.
I can buy the equipment to make an unlimited number of guns for far less than I can buy most new guns.
Relying on gun restrictions is the definition of fighting a losing battle.
