Form a national registry of firearms, which I think will promote more accountability from owners. It would also help law enforcement to monitor stockpiling of weapons, report stolen weapons, and connect weapons to crimes outside of local jurisdiction, which could prevent an attack, perhaps.

Require anyone buying ammo to present a current license to own a firearm. That way a person can't purchase ammo for an illegal firearm, or a firearm that belongs to someone else that they may have access to.

Close all loopholes that enable someone to purchase a weapon without a waiting period or background check or official registration. You can make private purchases of firearms in many states and at gun shows without any type of oversight, especially in states that don't require a license at all.

Make rifle and handgun legislation mirror each other. That way if it's illegal in your state to carry a concealed handgun, it would be similarly illegal to conceal a long gun.

These are just some of my own ideas.
