Mossberg 56436 500 All 20 Gauge 3" 6-Round Shotgun

The Mossberg 56436 500 All 20 Gauge 3" 6-Round Shotgun is a versatile, pump-action platform purpose-built for tactical, hunting, and home-defense applications where reliability and modularity matter most. Chambered in 20 gauge, this shotgun delivers reduced recoil compared to 12-gauge alternatives while maintaining sufficient payload for law enforcement, military training, and civilian defensive scenarios. Law enforcement agencies and military trainers have long favored the Mossberg 500 platform for its legendary durability, component interchangeability, and simple operation under stress.

Built on the proven Mossberg 500 receiver architecture, the 56436 features a 3-inch chamber that accepts standard 2.75-inch and premium 3-inch 20-gauge ammunition for expanded ballistic options. The 6-round magazine tube provides adequate capacity for tactical reloads and follow-up shots, while the smooth pump action cycles reliably across a full range of load pressures—critical in high-stress situations where feeding reliability determines outcome. At 8.6 pounds, the shotgun balances controllability with substantial mass for reduced felt recoil and faster shot-to-shot transitions. The modular design accepts a wide aftermarket ecosystem of barrels, stocks, forends, and optic mounts, enabling field customization for specific roles.

This platform suits law enforcement trainers, military cadre, armed security professionals, and serious civilian shooters seeking a versatile, low-recoil shotgun that demands minimal mechanical training to operate. The 36.5-inch overall length positions it favorably for vehicle storage, building clearance, and tactical transportation without sacrificing sight radius or stock-mounting flexibility. Mossberg 500-pattern accessories—barrels, chokes, stocks, and rail systems—remain widely available through duty and commercial channels, ensuring long-term parts availability and upgrade pathways. The 20-gauge platform is particularly effective for training programs where shooter volume and ammunition cost justify the gauge selection.
