Dad had an old Remington (I think) 12 gauge that could hold 7 shells. Had a wooden plug that had to stay in it so it could only hold 3, IIRC. Kicked like mule too, a padded shooting jacket was required or you would have a blue/purple shoulder after a good Quail hunt.
My dad had a Browning Sweet 16. Semiautomatic, 3 shot magazine.
That would be banned under such a law…
