It is not illegal to purchase or own a gun in those states.
Sure and you can get a concealed carry too, right?
Denying the outrageous infringement of the 2nd amendment that happens in states like I listed makes you quite suspect.
There are many guns that are illegal to purchase and illegal to own in Kalifornia. The Ninth Circus Court has upheld Kalifornia's claims that there is no individual right to have a firearm. There is no reason to believe that the anti-gun Demoncrats here will stop in their efforts without something very dramatic happening.
