mossberg pump shotguns

I just picked up a Mossberg 500 Tactical. Any suggestion on accessories for HD and barrel suggestions for hunting. Links would be great if you have had dealings with the companies. Thanks in advance. - Simon

Bought the shotgun at a pawn shop for $80 cash. Had to remove some light rust from the barrel. Purchased an ATI pistol grip for $15 NIP. grand total of $95. I looked up on mossberg's website and saw they are selling a cruiser for 350. I was quite pleased with my self.
