My girlfriend bought me a new shotgun. The problem is I know very little about shotguns. Pistols, & assault rifles are what I prefer to shoot. The shotgun is stamped BENELLI ARMI SPA URBANI ITALY on the barrell. On the reciever it 's stamped HECKLER & KOCH, INC.- CHANTILLY,VA, on the right side. On the left side it's stamped SUPER 90. It has a flshlight mounted in the pump activated by a pressure switch on the right side of the pump, a pistol grip & shoulder stock, & side saddle. It takes 8+1. Any reason why there are two manufactuers name on the same gun? Any info on this shotgun is appreciated.
