Amendments 2 through 10 always were meant to apply to the States since there is no mention of Congress being prohibited from the actions mentioned in those amendments.
I find it odd that you think States can enact any gun laws they want since the 2nd "Wasn't meant to apply to the States". Oh, wait, its just that the FIRST wasn't meant to apply to the States, right? That opens up an entirely different can of worms considering that States could ban whatever print they wish.
