Mossberg SA-20 75780 20 Gauge Semi-Auto Shotgun 20" Barrel 4+1

The Mossberg International SA-20 delivers reliable semi-automatic performance in a compact 20-gauge platform designed for versatility and control. This gas-operated shotgun combines the manageable recoil of 20-gauge ammunition with rapid follow-up shot capability. The pistol grip stock configuration provides enhanced control during dynamic shooting situations.

What Makes This Different

Unlike traditional sporting shotguns, the SA-20 features a tactical-style pistol grip stock that improves handling in confined spaces and allows for more intuitive point-and-shoot operation. The gas-operated system cycles reliably with both 2¾" and 3" shells, providing ammunition flexibility that pump-action alternatives cannot match. The 20" barrel length strikes an optimal balance between maneuverability and ballistic performance.

Key Features

• Gas-operated semi-automatic action cycles 2¾" and 3" 20-gauge shells
• 20" barrel with matte blued finish resists corrosion and glare
• Fixed pistol grip stock enhances control and reduces felt recoil
• 4+1 capacity provides adequate firepower for most applications
• 3" chamber handles high-velocity loads for extended range capability
• Standard receiver accepts most aftermarket accessories and optics
• Lightweight design reduces fatigue during extended use

Field performance demonstrates consistent cycling across various ammunition weights and manufacturers. The 20-gauge platform generates approximately 40% less felt recoil than comparable 12-gauge models while maintaining effective terminal ballistics out to 40 yards with appropriate loads. Weather testing shows reliable function in temperatures from -10°F to 120°F with proper maintenance.
