Mag Msbrg 590m 12ga 20rd Dbl Stk Blk

The Mossberg 590M 12-gauge 20-round double-stack black magazine is a factory-original accessory engineered for the Mossberg 590M mag-fed shotgun platform. Built to the same exacting standards as OEM equipment, this polymer-bodied magazine delivers the round capacity and reliability required for serious tactical, defensive, and training applications where magazine-fed shotgun systems demand consistent performance under operational conditions.

The 20-round capacity provides extended trigger time between reloads—a critical advantage in training scenarios, home defense scenarios, and professional applications where minimizing magazine changes improves both speed and operational efficiency. The double-stack configuration optimizes round count while maintaining reliable feeding through the 590M's proprietary magazine-well design. Polymer construction keeps weight minimal at 1.94 pounds while resisting corrosion in varied environmental conditions. The magazine is chambered for 2¾-inch shells only, matching the standard ammunition specification for 12-gauge tactical applications. Compatibility is precise: this magazine functions exclusively with the Mossberg 590M mag-fed model and will not function in other Mossberg shotgun platforms or legacy tube-fed designs.

Operators, law enforcement personnel, and shotgun enthusiasts who rely on the 590M for patrol duties, dynamic training, home defense, or competitive shooting applications depend on factory magazines to maintain the reliability baseline their firearms are designed to deliver. Aftermarket magazines introduce variable quality and potential feeding issues; OEM Mossberg magazines ensure optimal fit and function lifecycle after lifecycle.

For shooters who operate the Mossberg 590M mag-fed shotgun system, carrying multiple original-equipment magazines is standard practice. This magazine is the trusted choice for maintaining the performance standard Mossberg engineered into the platform.
