The Winchester SX4 Waterfowl Hunter is a gas-operated semi-automatic shotgun built for serious duck and goose hunters who demand reliable performance in harsh conditions. This 12-gauge 3.5" chamber gun features the proven Active Valve system that Winchester refined from the SX3, delivering smooth cycling across a wide range of loads while maintaining the balance and handling that matter when you're working birds over decoys or timber.
The 26" barrel wears Mossy Oak Bottomlands camouflage—a time-tested pattern that blends seamlessly in marsh vegetation and bare timber where waterfowl hunters spend their season. The ventilated rib helps with sight picture and heat management, while the chrome-plated chamber and bore protect against the corrosion that comes with wet, saltwater, and steel shot. Winchester equipped this gun with practical features born from real hunting: a TruGlo fiber-optic sight for low-light conditions, the new Inflex recoil pad to soften felt recoil, length-of-pull spacers to dial in your fit, and a reversible safety for left- or right-handed operation.
Handling and speed count in waterfowl season. The SX4 features a larger cocking handle and bolt release for faster manipulation when you're wearing heavy gloves, and the trigger guard opening is widened to let your finger work without fumbling. Three Invector-Plus choke tubes ship with the gun, giving you flexibility to adjust your pattern for different distances and shot sizes.
At 6 lbs 12 oz with a 14.25" length of pull and moderate drop dimensions, the gun points naturally and won't wear you out during a long morning in the blind. Sling swivel studs are already installed, and the 4-round magazine capacity keeps you ready for fast-action situations.

Yes. The 3.5" chamber safely cycles both 3" and 3.5" loads, and the Active Valve system adjusts operation across a range of load power levels.
The safety button is reversible, making it accessible for both left- and right-handed hunters. However, review the full specifications and handling to confirm the gun meets your specific needs as a left-handed shooter.
Mossy Oak Bottomlands is a camouflage pattern designed to blend in marsh and timber environments where waterfowl hunt. The finish is applied to the receiver, barrel, and stock for complete concealment.
