The Mossberg 590M Double Stack 15-Round Magazine is engineered for shooters who demand higher capacity without sacrificing handling. Unlike traditional single-stack shotgun magazines that force you to choose between firepower and ergonomics, this 15-round design stacks shells in a double-column arrangement—keeping the magazine profile compact while delivering serious round count. Whether you're running defensive drills, competing in 3-gun, or prepping for field use with your 590M pump action, this magazine gives you the efficiency serious shooters expect from a modern tactical shotgun platform.
Built tough for hard use, the magazine features hardened steel feed lips over-molded to steel shell ramps for reliable feeding of 2.75" shotshells. The proprietary self-lubricating polymer body resists corrosion and abuse, while heavy-duty ASTM-A-228 music wire spring maintains tension through hundreds of cycles. A removable floor plate makes cleaning and maintenance straightforward—no disassembly hassles when you need to clear debris or inspect internals. All steel components wear a tough black oxide finish to resist rust and wear.
Mossberg engineered the double-stack geometry to deliver better swing balance and control than competitor single-stack alternatives—a real advantage when you're tracking targets or moving between positions. The external molded grip design sits naturally in your hand during speed reloads. If you need flexibility, 590M magazines are also available in 5, 10, and 20-round capacities, so you can tailor your loadout to your mission.
