Never heard of it,Schweizer, but the pics show it's yet another revolver shotgun.
Like the Striker and Streetsweeper, chances are it has a lousy trigger with the DA feature needing to move all that ammo and metal, the lack of a decent stock means it will be harder to shoot than most. And, note the lack of sights.
The ones I've handled had all the balance of a cinder block.
Drum mags have their own set of problems and tend to catch on things in CQ.
