Requiring gun registration, buy a firearm anywhere else that from an FFL and no registrations is required
since the guys pointed out your mis-informed thoughts on all but this one, I'll tackle it. You do realize in several states it's against the law to sell a firearm to another individual without going through a gun dealer, don't you? And how about California, where you can't even walk into a store and pick up a couple boxes of ammo., pay and walk out? Let alone do that to buy a gun.
