The 590M offers magazine-fed convenience in the legendary Mossberg pump-action tactical platform. The shotgun and magazine are uniquely designed incorporating stabilizing ribs that engage the magazine directly to the receiver for a sure lockup. The features Mossberg tactical pump users expect are all there: dual extractors, twin action bars, positive steel-to-steel lockup, drilled and tapped receiver, ambidextrous safety, and a heavy-walled barrel.
