Mossberg 590M Pro 12Ga 11.5 Grs Tungsten 10Rd
The Mossberg 590M Pro is a 12-gauge pump-action shotgun built on the proven 590 platform, engineered for reliability in demanding situations. This short-barreled model features an 11.5-inch heavy-walled stand-off barrel finished in Cerakote Tungsten, a durable gray coating that resists abrasion and corrosion in harsh conditions. With a compact 24.5-inch overall length and the distinctive Aftershock bird's head grip, the 590M Pro is maneuverable in tight spaces while maintaining the pump-action handling that generations of shooters have trusted.
The 590M Pro ships with a 10-round detachable magazine—part of Mossberg's modular magazine system that lets you swap in 5, 10, 15, or 20-round options depending on your mission. Stabilizing ribs on the magazine engage the receiver for solid lockup every time. Under the hood, you get dual extractors, steel-to-steel lockup, an ambidextrous top-mounted safety, and twin action bars—the mechanical backbone that makes the 590 a workhorse across law enforcement, security, and professional roles.
The cylinder bore choke keeps patterns open at close range, matching the gun's purpose-built design. At 7 pounds, it balances controllability with substantive recoil management. A simple bead sight keeps your sight picture quick and intuitive. This is a shotgun built for function first, cosmetics second—the kind of tool that doesn't need a lot of explanation when the moment matters.

Frequently Asked Questions
What magazines are compatible with the 590M Pro, and can I swap them?
The 590M Pro ships with a 10-round detachable magazine, but Mossberg makes this shotgun's magazine system modular. Replacement and additional magazines are available in 5, 10, 15, and 20-round capacities, and they're designed to lock securely into the receiver via stabilizing ribs on each magazine.
Is the 590M Pro suitable for left-handed shooters?
Yes. The 590M Pro features an ambidextrous top-mounted safety, so both left and right-hand shooters can operate it comfortably without adjusting grip or reach.
What does "heavy-walled stand-off barrel" mean on this shotgun?
The barrel is built thick to withstand the stresses of close-quarters use and is designed for stand-off applications—situations where the muzzle may make contact with obstacles or barriers. The heavy wall construction adds durability and is paired with the Cerakote Tungsten finish for corrosion and wear resistance.
What ammunition does the 590M Pro chamber?
The 590M Pro has a 2.75-inch chamber, so it accepts standard 2.75-inch 12-gauge ammunition. Always verify ammunition compatibility and follow all manufacturer guidelines before loading and firing.
