Winchester Guns Sx4 Wgun 511289391 Sx4 Wtfwl 12 3 26 Wdlnd

The Winchester SX4 Waterfowl Hunter is a gas-operated autoloading shotgun built for hunters who need reliable, fast-cycling performance in wet conditions and marshland environments. The 12-gauge receiver is crafted from lightweight aluminum alloy and finished in classic Woodland camouflage, a time-tested pattern that blends seamlessly from flooded timber to cattail-thick marshes. This shotgun delivers the soft-shooting, proven operation that made Winchester's gas-driven platform a standard-bearer in waterfowl hunting—and the SX4 builds on that legacy with refinements to balance, controls, and internal components that make it a worthy successor to its predecessors.

Built around Winchester's Active Valve Gas System, the SX4 cycles reliably whether you're shooting light target loads or heavy waterfowl ammunition. The 26-inch barrel features a chrome-plated chamber and bore for rust and corrosion resistance—critical when steel shot and salt water are part of your hunt. A ventilated rib aids in sight acquisition and lets heat dissipate between shots. You get three Invector-Plus choke tubes (including full modified) so you can tailor your pattern for everything from close-quarters timber work to open-water passes.

Comfort and handling are thoughtfully addressed: the shotgun includes Winchester's new Inflex Technology recoil pad to soften felt recoil, length-of-pull spacers to dial in fit, and larger bolt handle and bolt release for faster manipulation in heavy gear. The reversible safety button works either way, and a larger trigger-guard opening accommodates gloved fingers. A TRUGLO fiber-optic sight tops the rib for fast target acquisition in low light, and sling swivel studs are already installed. The composite stock wears the same Woodland finish as the receiver and barrel, creating a cohesive, no-nonsense waterfowl gun.

Frequently Asked Questions

Will this shotgun handle both light target loads and heavy magnum shells?

Yes. The SX4 Waterfowl Hunter is chambered in 12-gauge with a 3½-inch capability, so it safely handles everything from standard 2¾-inch loads to full 3½-inch magnum shells. The Active Valve Gas System cycles reliably across the full range, and the chrome-plated bore stands up to the wear and corrosion from steel shot used in waterfowl hunting.

What choke tubes come with the SX4?

The shotgun includes three Invector-Plus choke tubes, with a Full Modified (FMIC) among them, giving you flexibility to adjust your pattern for different distances and hunting situations.

Is the SX4 good for hunting in cold, wet conditions?

The SX4 Waterfowl Hunter was designed for exactly that environment. The chrome-plated chamber and bore resist rust and corrosion from saltwater and wet conditions, the Woodland camouflage finish works across marsh and timber habitats, and the larger bolt handle and safety button remain operable when you're wearing heavy gloves.

What's included in the box?

The SX4 comes with three Invector-Plus choke tubes, the TRUGLO fiber-optic sight mounted, the Inflex recoil pad installed, length-of-pull spacers, sling swivel studs, and a reversible safety button. You're ready to sling it and hunt.
