I don't know, they are factory sights, front sight is a long green tube, about an inch and a quarter on a bracket that slides over the barrel rib and the rear sight is two red tubes on a bracket that is screwed to the rib and is adjustable. There is no writing on either sight. Perhaps you could contact Mossberg and ask them what they use. I wouldn't be surprised if there were after market sights of the same configuration. In the link, the sights on the left are the turkey gun sights, that red on both sides with the green in the center really catches your eye in dim light. http://www.mossberg.com/category/series/935-magnum/
