If you are chemically dependent or an alcoholic, you cannot have a gun.
If you defend yourself against a minority attacker, you are guilty until proven innocent.
If you live in certain cities, you can only have long guns, and not hand guns.
If you go into certain buildings, you cannot have a gun, many of the buildings being public buildings.
If you have a certain kinds of guns, you need a license that is granted by the whim of a sheriff in some states and counties.
If you want guns with a certain capacity of magazine, you cannot have them in many places.
If you want a pistol, you need to be 21 (being an adult of military service age is not good enough).
If you dont convince law enforcement that you have a special need to carry a weapon, then in some places they may willy-nilly deny you the right to use or carry one.
If you do not pay a tax when you purchase the weapon, you cannot have one.
If you do not use ammunition made of non-lead components, you may not have it in some places like California.
If you want a weapon that fires more than once with each trigger pull, you need a special license.
If you want to carry a pistol in many places, you much produce your fingerprints and submit your name to law enforcement.
If you want a pistol, a record must be kept by the commercial seller for a certain length of time for review by law enforcement purposes.
If you use your weapon to defend yourself, you will need to bear the burden of proving, in a practical sense, that you were justified, and no one will reimburse you for your time or costs.
If you own a pistol in some states, you must pay a fee for the privilege.
If you own a pistol in some states, you must pay for training and a certificate of that training.
If you want a weapon you may not bring it on school grounds, government buildings, or other locations, even if there is no screening for weapons.
If you buy and sell weapons and ammo, you need a license.
In many places you must give the registration of the gun to the local law enforcement.
Etc. Etc. Etc.
But if you require an ID to vote, then you are deliberately trying to prevent people from voting.
