There is a legal non-NFA short-barrel shotgun type now.

All the big makers are now making short shotguns in this class with ATF approval.
Very nice. The one problem I would have, is the pistol grip in California. I don’t believe they allow them.
Now I may have that mixed up with other weapons, but I don’t believe they’d allow this here.
Other than that, that does look like a great little weapon for close in work.
Thank you.
