FOID?
Wow, you all were right! .
Wally World claimed there's a new law that says they can only sell shotgun ammo to non-residents (which I did buy), not that they had any .45.
I did find another smaller operation that was more than willing to sell me .45 in FMJ and JHP, though the price was through the roof. 22 for MagTech FMJ's and 25 for a 20-pack of JHP.
