TriStar Cobra III Field 410 Gauge Semi-Auto Shotgun 28" 5+1 Walnut

The TriStar Cobra III Field 410 Gauge delivers reliable semi-automatic performance in a lightweight platform designed for upland hunting and pest control. This gas-operated shotgun cycles 2.75" and 3" shells consistently while maintaining the manageable recoil that makes .410 bore ideal for youth shooters and small game hunting.

What Makes This Different

Unlike many budget .410 shotguns that rely on break-action designs, the Cobra III Field uses a proven gas-operated semi-automatic system that enables faster follow-up shots. The 28" barrel provides superior velocity retention compared to shorter alternatives, delivering approximately 50-75 fps more muzzle velocity than 26" barrels. The included MobilChoke system offers versatility that fixed-choke competitors cannot match, allowing hunters to adapt from tight patterns for turkey to open patterns for dove.

Key Features

• Gas-operated semi-automatic action cycles both 2.75" and 3" .410 shells reliably
• 28" chrome-lined barrel with ventilated rib maximizes velocity and sight picture
• 5+1 capacity magazine provides extended shooting without reloading
• Three MobilChoke tubes included (typically IC, M, F constrictions)
• Turkish walnut stock with 14" length of pull fits most adult shooters
• Matte black receiver and barrel finish resists corrosion and glare
• Fiber optic front sight enhances target acquisition in low light

Field testing demonstrates consistent cycling with standard velocity loads from major manufacturers including Federal, Winchester, and Remington. The gas system adjusts automatically to different shell lengths and power levels, eliminating the need for manual regulation. Hunters report effective patterns out to 35 yards with appropriate choke selection, making this shotgun suitable for squirrel, rabbit, dove, and pest control applications. The synthetic trigger guard and lightweight aluminum receiver keep total weight manageable for extended carry.
