Just picked up a used 535 this morning. I haven't had a chance to shoot it yet but I'm not worried (its a mossberg) just excited! I traded a bow for it. It came with the field barrel and the slug barrel. Also got a case and a box o shells. Any other 535 owners here that can give me the run down in this shotgun? I had a master mag 880c that worked flawlessly and then got a h&r single shot 12 gauge...ouch. I sold must if my guns awhile back for reasons I'd rather not discuss and am rebuilding my collection. I thought this would be a great start. I'm kicking around the idea if selling the slug barrel to set it up with a 500 mag tube and 20 inch barrel for hd purposes. Any input for other methods would be appreciated. Thanks!
