You can obtain a revolver, semi-auto pistol with a less than ten round magazine, a bolt or lever action rifle or a shotgun with a less than five round magazine. Everything else is prohibited. Your ability to purchase/possess firearms can also be removed or prevented by the local government if it decided it has "just cause" which isn't defined other than a laundry list of offenses ranging from offenses in other states to possession of banned firearms or magazines. You also need a firearms permit to buy pepper spray or any other non-lethal protective device. In other words, your rights are subject to state control.
