Mossberg 590S Compact 12GA Pump Shotgun 18.5" 9+1 Synthetic

The Mossberg 590S Compact delivers the proven reliability of the 590 platform in a more maneuverable package. This 12-gauge pump-action shotgun combines the versatility of accepting both 2¾" and 3" shells with a compact 18.5" barrel length that excels in confined spaces and tactical applications.

What Makes This Different

The 590S series represents Mossberg's evolution of their legendary 590 design, incorporating dual extractors and an enhanced feeding system that reliably cycles shells of varying lengths without adjustment. Unlike standard shotguns that may struggle with mixed ammunition, the 590S maintains consistent ejection timing across different shell types. The drilled and tapped receiver accepts optics and accessories directly, eliminating the need for aftermarket modifications.

Key Features

• Dual extractors ensure reliable ejection of 2¾" and 3" shells without modification
• 18.5" barrel with cylinder bore provides optimal spread for close-range applications
• 9+1 capacity with 2¾" shells, 8+1 capacity with 3" shells
• Drilled and tapped receiver accepts Weaver/Picatinny rail systems and optics
• Synthetic stock and forend resist weather and chemicals while reducing weight
• Ambidextrous tang safety accessible to both right and left-handed shooters
• Heavy-walled barrel rated for steel shot and high-pressure loads

Field testing demonstrates consistent cycling across ammunition types, from light target loads to heavy waterfowl rounds. The compact dimensions make this shotgun suitable for home defense, patrol duty, and hunting in dense cover. The synthetic furniture maintains zero shift in temperature extremes and resists impact damage better than traditional wood stocks.
