It's not an automatic weapon.
Though automatic weapons, aka machine guns, are perfectly legal. Get a permit, buy one. Federally, ten or so states ban them.
14 round magazine, sounds ominous, but you are in more danger from someone carrying a wheelgun who can place 5 or 6 shots.
Aliens purchasing firearms. While I recognize they will be able to purchase them illegally, that's just plain stupid. I'd support restricting firearms ownership for non-citizens for a period of years, one, five, whatever, come up with a bill.
But Rudy didn't propose that, he didn't focus on aliens, he focused on gunowners. Legal gunowners, not illegals.
You will see at the link that he very much proposed reasonable measures and not a ban on everyone.
In my opinion the criticism of Florida is very valid.
In his own words.

Unrestricted gun purchase is an impossibility in the practical World in which we live. Sad but true.
