Mossberg shotguns and rifles that earn the Professional Series designation undergo an enhanced assembly and quality control process, have special finishes and features, and are optimized for performance. Two new versions of Mossberg’s 590M Magazine-Fed pump actions join this exclusive series with option of black or orange synthetic furniture (compact and Magpul® models available); Cerakote® protective finish on barrel, receiver, and magazine tube; and this groundbreaking 12-gauge, 2.75-inch platform is fed from the first production double-stacked magazine made for pump actions.

Mossberg’s 590M Mag-Fed design utilizes integral stabilizing ribs on the magazine which engage directly to notches engineered into the receiver for a positive lock-up. The all-steel, ambidextrous magazine release button and housing are strategically positioned in front of the trigger guard and will not interfere with cycling of the action. Accessory 590M double-stack magazines are available in 5, 10, 15, 20-round capacities to provide for greater capacity in shorter magazine length than competitor’s single-stack design and the ability to quickly reload or change shell type – slugs, buckshot, or less lethal.

The double-stack 590M magazines are constructed with hardened-steel feed lips, over-molded steel shell ramps and an anti-cant, rounded follower to ensure reliable feeding. Additional features include an easy-grip, molded external shell; proprietary self-lubricating polymer magazine body; heavy-duty ASTM-A-228 music-wire magazine spring for prolonged service life; removable floor plate for ease of cleaning; and durable black oxide finish on the steel components.

Key Features of the 590M Pump-Action Shotgun Professional Series:

• Optic-ready receiver (RMSc footprint) which is covered by certain patents and patents pending. Simply remove the rear Optimized Ghost Ring sight for access to optic cut.
