Mossberg 590M 12 Gauge Shotgun 10+1 Capacity 18.5" Barrel

The Mossberg 590M revolutionizes tactical shotgun design with its magazine-fed system, delivering rapid reloads and sustained firepower when seconds count. This 12-gauge platform abandons traditional tube feeding for detachable box magazines, providing tactical advantages in high-stress situations.

What Makes This Different

Unlike conventional pump-action shotguns that require individual shell loading, the 590M accepts detachable magazines for lightning-fast reloads. The system accommodates 5, 10, 15, and 20-round magazines, dramatically reducing downtime between engagements. This magazine compatibility transforms the shotgun from a limited-capacity platform into a high-volume fire support weapon.

Key Features

• Detachable box magazine system accepts 5, 10, 15, and 20-round magazines
• 18.5-inch heavy-walled barrel with cylinder bore choke
• Dual extractors ensure reliable ejection with various ammunition types
• Anti-jam elevator prevents double-feeding during rapid cycling
• Picatinny rail integrated into receiver for optics mounting

Field performance demonstrates the 590M's reliability across ammunition types from light target loads to heavy 3-inch magnum shells. Law enforcement agencies report consistent cycling with reduced-recoil rounds and standard buckshot loads. The magazine system eliminates the fumbling associated with tube loading under stress, while the proven 590 action maintains the platform's reputation for dependability in adverse conditions.
