The ONLY legitimate "gun law":
Compel the Justice Dept. to register all felons (who have not had their rights legally reinstated) and publish a list of them – updated daily. Then prohibit (under penalty of law) all licensed gun dealers from selling guns or ammo to them. All law-abiding (non-registered-felon) adults simply bring cash, show ID (as they would to vote, or rent a car), and leave with their purchase in hand. Register felons – NOT law-abiding citizens.
