The Mossberg 590M is a magazine-fed pump-action shotgun built for shooters who demand modern ergonomics and serious capacity without compromise. Unlike traditional tube-fed shotguns, the 590M uses double-stack magazines—a first for production pump-actions—giving you 10 rounds in a footprint that won't bog down your gun. Pair that with a rock-solid 12-gauge platform that's earned its reputation across decades of service, and you've got a tactical shotgun that blends proven reliability with next-generation features.
What makes the 590M stand out on the range or in the field is its thoughtful modern design. The ambidextrous AR-style rotary safety sits naturally under your thumb, while the compact forend keeps things tight and controllable. The integrated heat shield built into the 18.5" barrel means you can operate hard without worrying about scorched hands. Five positions of adjustment on the stock let you dial in your fit, and the Magpul MBUS backup sights are already mounted and ready to go—no zeroing other optics unless you choose to. Top-mounted Picatinny rail accommodates AR-pattern optics if you want to add glass later. QD ports on the stock base give you quick-detach options for slings or accessories.
Inside, the 590M doesn't cut corners. Dual extractors, positive steel-to-steel lockup, and twin action bars deliver the smooth, reliable cycling you expect from Mossberg. The flat-profile trigger breaks clean and predictable. Magazines lock in securely with stabilizing ribs, and you can swap them with a lever-style release that's fast and intuitive. The Accu-Choke system lets you tune performance for different loads.
Whether you're running three-gun matches, home defense, or training hard, the 590M brings tactical shotgun thinking to a platform that refuses to quit.
