Mag Msbrg 590m 12ga 10rd Dbl Stk Blk

The Mossberg 590M 12-gauge 10-round double-stack magazine in black polymer is a factory OEM replacement magazine engineered for the Mossberg 590M mag-fed shotgun platform. This magazine delivers the same fit, function, and reliability as your original equipment, ensuring zero reliability compromises when deployed in the field.

Built from durable polymer, the magazine is rated for 2-3/4-inch shells exclusively, a critical specification for the 590M platform. The double-stack configuration maximizes round capacity while maintaining a magazine profile compatible with the shotgun's mag-fed system. At 1.44 pounds when loaded, the magazine contributes manageable weight to the gun's handling characteristics during extended use. The polymer construction resists corrosion in varied environments—a significant advantage over steel alternatives when operating in humid or salt-air conditions.

This magazine is purpose-built for shooters and operators who field the Mossberg 590M in defensive, training, or tactical roles. Law enforcement agencies and civilian shooters running mag-fed 590M systems benefit from having backup magazines on hand, as magazine failure is the most common point of failure in semi-automatic shotgun operation. Mossberg factory magazines ensure that magazine-related malfunctions remain virtually non-existent when maintained properly.

The 590M mag-fed shotgun offers faster reloads and higher capacity than traditional tube-fed designs, making aftermarket and factory magazines essential consumables for any serious operator running the platform. Maintaining a minimum of two to three spare magazines is standard practice for duty, competition, or home-defense scenarios.
