The Mossberg 590M Double Stack 10-Round Magazine is purpose-built for shooters who want genuine capacity without sacrificing handling. Unlike single-stack tube designs that force you to choose between ammo count and swing speed, this double-stack 12 gauge magazine holds 10 rounds of 2.75" shells in a package that keeps your pump action nimble and balanced. Whether you're running tactical drills, home defense scenarios, or clay courses, the compact profile means faster transitions and better control when it matters.
Built for the harsh realities of serious shooting, the magazine features hardened steel feed lips bonded over molded steel shell ramps—the parts that take the most punishment get the most durability. The proprietary self-lubricating polymer body handles mud, sand, and salt spray without gumming up, while the heavy-duty ASTM-A-228 music wire spring delivers consistent feeding through hundreds of cycles. Steel components wear a tough black oxide finish to resist corrosion in field conditions.
The removable floor plate makes cleaning and maintenance straightforward—no stripped fasteners, no trapped debris. The external molded grip surfaces let you manipulate the magazine with wet or gloved hands. Part of Mossberg's modular 590M system, you can run 5, 10, 15, or 20-round magazines on the same gun, giving you real flexibility for different tasks without swapping platforms.

This magazine is designed for the Mossberg 590M pump action shotgun. The 590M system accepts interchangeable magazines in 5, 10, 15, and 20-round capacities, all built to the same interface standard.
No. This magazine is designed for 2.75" shotshells only. Do not attempt to use it with 3" or 3.5" ammunition.
The double-stack configuration stacks rounds side-by-side rather than end-to-end, creating a shorter, more balanced magazine relative to its capacity. This translates to faster swing speed and easier handling compared to long single-stack tube designs holding equivalent rounds.
Yes. The removable floor plate allows you to disassemble the magazine for thorough cleaning and inspection without tools.
