Mossberg 590S 12 Gauge Shotgun 20" Barrel 3" Chamber Multi-Capacity

The Mossberg 590S transforms shotgun versatility with its patented multi-capacity magazine system that accepts 2.75", 3", and mixed shell loads without modification. This tactical shotgun delivers reliable performance across law enforcement, home defense, and sporting applications with its proven pump-action design.

What Makes This Different

Unlike traditional shotguns limited to single shell lengths, the 590S accepts any combination of 2.75" and 3" shells in the same magazine tube. The patented magazine system automatically adjusts capacity: 13+1 with 2.75" shells, 8+1 with 3" shells, or 7+1 with mixed loads. This eliminates the need for separate firearms or magazine modifications when switching between different shell types.

Key Features

• Multi-capacity magazine system accommodates 2.75" and 3" shells simultaneously
• 20" matte blued barrel with cylinder bore choke for tactical applications
• Black anodized aluminum receiver with laser engraving for durability
• Synthetic stock and forend resist weather and impact damage
• Dual extractors and positive steel-to-steel lockup ensure reliable cycling

Field testing demonstrates consistent cycling across shell types from light target loads to heavy 3" magnum rounds. The 590S maintains the reliability standards expected in military and police applications while offering unprecedented ammunition flexibility. Law enforcement agencies report successful deployment in both urban and rural environments, with the multi-capacity system proving valuable when ammunition types vary during extended operations.
