The Winchester SX4 Waterfowl Hunter delivers rapid follow-up shots and all-weather reliability for serious waterfowl hunters. This 20-gauge semi-automatic shotgun handles 3-inch magnum loads with Winchester's Active Valve gas system that cycles consistently across different shell weights and conditions.

What Makes This Different

The Active Valve gas system automatically adjusts to different loads without manual intervention, eliminating the cycling issues common in other semi-automatic shotguns. The chrome-plated chamber and bore resist corrosion from wet hunting conditions, while the oversized bolt handle and bolt release provide positive operation with gloved hands. The receiver is drilled and tapped for scope mounting, offering versatility beyond traditional waterfowl hunting.

Key Features

  • Active Valve gas system cycles 2¾" to 3" shells reliably
  • Chrome-lined chamber and bore for corrosion resistance
  • Realtree Timber camouflage pattern for concealment
  • Three Invector-Plus choke tubes included (Full, Modified, Improved Cylinder)
  • 4+1 capacity with drop-out trigger group for easy cleaning
  • 26" barrel optimized for waterfowl hunting ranges
  • TruGlo fiber-optic front sight for fast target acquisition
Field performance centers on the gun's ability to handle varying ammunition types without adjustment. The 26-inch barrel provides sufficient velocity for long-range shots while maintaining maneuverability in tight blinds. The synthetic stock resists moisture absorption and temperature changes that affect wood stocks during extended hunts. Hunters report consistent cycling with everything from light target loads to heavy steel shot magnums.
