And to be fair the no fly list is probably going to make bugger all difference to mass shootings and other gun crime because they are not on any terrorist watch lists...
Not really knowing the requirements for testing to get a firearm in the US I'm not going to propose anything specific but certainly things like psychological testing, interviews, "reasons for needing one" and limits based on requirements seem like good starting points, along with the "gun show loophole", which just seems ripe for abuse.
So basically (in all but 18 states) as long as you aren't a a licensed seller (so a gun shop then?) you can sell or give weapons to anyone without any kind of check, perfectly legally.

Which explains why the government have no idea who has what.
You're forgetting the part where it's a right.
If they can require psychological tests, interviews, reasons, for gun ownership then they can require those same things for any other right, ie free speech etc...
No thanks.
To be clear, in order to get a 'License to Carry', which I have, in Texas you are required to pass both a State and FBI background investigation which includes any psychiatric records.
Now, as I've said here before, I'd like to fix the 'over the fence' sales problem, but there's just no way to do that without putting the constitution through a shredder. It's not going to happen.
Blaming the gun for gun violence is the same as blaming the car for drunk driving deaths. IOW, it's beyond insane. The problem, as with almost everything, is people. Now, how do we fix that??
Don't ever forget, in America gun ownership is a right. You don't have to like it, but you'd better find a way to deal with it because it's not going anywhere.
Not one single restriction that the anti-gun lobby has managed to push through has had any measurable effect on gun violence. Prove me wrong. (you can't do it, as you can't prove a negative.). But why is that really? It's because the problem isn't guns, it's people.
