Bud's has a bunch of police trade ins Mossberg 590 Mariners. They are SS, 9 shot, accept 2-3/4 or 3" shells and supposedly have very little range time, just carry time. They're asking $359. According to my value books, that is on the high side, but still about $100 (or 25-30%) less than a new one. I'd like a good truck SG that I could haul around w/ little worries of it's well being. Also love the capacity and heard it blasts slugs like a dream. So is it worth it??? Get it?
