Mossberg has added a 590M Standoff pump action to its line of 590 magazine-fed firearms. This 12-gauge, 2.75-inch pump action features a 14.25-inch heavy-walled, standoff barrel and is fed from the first production shotgun double-stack magazine. The 590M offers added versatility with the convenience of 5, 10, 15, 20-round accessory magazines.
