Mossberg Double-Stack Magazine for Mossberg 590M Mag-Fed Shotgun 10/

The Mossberg Double-Stack Magazine for Mossberg 590M Mag-Fed Shotgun (10-round capacity) is a high-impact polymer magazine purpose-built for the Mossberg 590M shotgun platform. This is the factory-original magazine designed specifically for operators and LEOs running the 590M as a primary duty or training tool, engineered to deliver consistent, reliable feeding of 12-gauge ammunition in both rapid-deployment and sustained-fire scenarios.

Built from hardened steel internal components and a self-lubricating polymer body, this double-stack magazine delivers ten rounds of 12-gauge capacity in a compact footprint. The proprietary design eliminates the need for manual lubrication while maintaining consistent round stacking and feeding geometry—critical when magazine reliability directly affects mission success. The polymer construction resists corrosion and reduces overall system weight compared to traditional steel tube magazines, without sacrificing durability in high-round-count training or operational environments.

This magazine is ideal for patrol officers, tactical teams, and serious shotgun competitors who depend on the Mossberg 590M platform. Whether conducting low-light entry drills, running carbine courses, or maintaining proficiency on the range, operators benefit from the increased capacity and reliability of factory-matched ammunition storage. The 590M magazine-fed system eliminates tube-loading delays and allows rapid top-off reloads during training or deployment, a significant operational advantage over traditional pump-action shotgun designs.

The Mossberg 590M itself represents a departure from legacy shotgun ergonomics, bringing detachable-magazine convenience to the shotgun world. This magazine is the direct-fit solution for that platform—no adapters, no compatibility guessing. Mossberg engineered it to OEM specification and tolerances, ensuring function in the shotgun it was designed for.
