Mossberg 940 Tactical 12 Gauge Semi-Auto Shotgun 18.5" 4+1

The Mossberg 940 Tactical delivers rapid-fire reliability for tactical applications with its gas-operated semi-automatic action and compact 18.5-inch barrel configuration. This 12-gauge platform combines proven Mossberg durability with enhanced cycling speed for competitive shooting and tactical operations.

What Makes This Different

The 940 series represents Mossberg's evolution beyond traditional pump-action designs, incorporating a self-regulating gas system that cycles both light target loads and heavy magnum shells without adjustment. Unlike competitors requiring manual tuning, this system automatically compensates for varying shell pressures. The oversized bolt handle and ambidextrous safety accommodate rapid manipulation under stress while maintaining the familiar Mossberg tang safety location.

Key Features

• Gas-operated semi-automatic action with self-regulating system
• 18.5-inch barrel with cylinder bore optimized for tactical loads
• 4+1 capacity with 3-inch magnum shell compatibility
• Oversized bolt handle and charging handle for positive manipulation
• Picatinny rail system for optics and tactical accessories
• Ambidextrous tang safety with crossbolt trigger guard safety
• Synthetic stock and forend with textured grip surfaces

Field performance demonstrates consistent cycling across shell weights from 2.75-inch target loads to 3-inch magnum buckshot. The 18.5-inch barrel length provides optimal balance between maneuverability and velocity retention for tactical scenarios. Corrosion-resistant finish withstands harsh environmental conditions while the synthetic furniture resists impact damage during transport and storage.
