Legality of 20 round drums for 12 gauges?

Promag makes them for some shotgun(s)...

Someone had sell a while ago that 20 round drums were considered 'streetsweepers' by law or something and banned?

Doesn't sound right....can anyone clarify?

As long as you don't have BOTH a folding stock AND a drum magazine, you should be fine.
