One of the newest members of the Mossberg Professional Series is the Mossberg 590M Breacher Professional Series, a 12-gauge, 2.75-inch pump action that is fed from a double-stack magazine. The design of the 590M provides balance and weight distribution and increased capacity while also allowing for the more compact conditions often required for breaching.

Mossberg’s 590M Mag-Fed shotgun features a detachable magazine with integral stabilizing ribs, which engage the magazine directly to notches engineered into the receiver for a positive lock-up. The all-steel magazine release button and housing are positioned in front of the trigger guard and will not interfere with cycling of the action. 590M compatible magazines are available in 5-, 10-, 15-, 20-round capacities for added versatility in selecting capacity or specific load.

The 590M is fed from double-stack magazines 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. This proprietary double-stack magazine design provides greater capacity in less magazine length versus competitor’s single-stack magazines.

Key Features of the 590M Breacher Professional Series:

• 11.5-inch heavy-walled, stand-off barrel with cylinder bore.

• One-piece construction of the stand-off barrel, machined integrally to the barrel.

• Mossberg’s Aftershock bird’s head grip which minimizes recoil and ensures a firm, sure grip.

• Cerakote Tungsten metal exterior finish, a polymer-ceramic coating that provides added corrosion and superior abrasion resistance.

• Oversized and redesigned top-mounted safety with highly visible red indicator and easily operated by right or left-handed shooters.

• Compact forend that utilizes M-LOK-compatible slots for mounting accessories to sides and bottom.

• Drilled and tapped receiver.

• One five-round detachable, double-stacked magazine. Accessory magazines available in 10-, 15-, and 20-round capacities (sold separately).

• Like all 590 pump actions, the 590M Breacher has dual extractors; steel-to-steel lockup; and twin action bars.
