Winchester Guns Sx4 Wgun 511305292 Sx4 Lh 12-3.5 28 Btmlnd

The Winchester SX4 left-hand 12-gauge autoloader brings serious waterfowl credentials to left-handed shooters who've waited too long for a semi-auto built their way. This gas-operated shotgun uses Winchester's proven Active Valve system—the same reliable platform that earned the SX3 and SX2 their reputation in the marsh—paired with Mossy Oak Bottomland camouflage that's been trusted by hunters for decades. With a 28-inch barrel, 3.5-inch chamber capability, and ergonomic controls designed for lefty operation, the SX4 LH handles the speed and patterns serious duck and goose hunters demand.

Left-handed shotgun options have historically meant compromise: buying right-hand models or waiting for limited availability. The SX4 LH is the mirror-image response—not a retrofit, but a purpose-built platform. The larger cocking handle, bolt release, and reversible safety button make the gun faster to operate in the blind without fumbling. The TRUGLO fiber-optic sight sits atop the ventilated rib, giving you a fast bead picture in low light. Composite stock with length-of-pull spacers means you can dial fit to your frame, and the Inflex recoil pad absorbs the snap of heavy 3.5-inch loads.

Choke flexibility rounds out the package: three Invector-Plus tubes (including full, modified, and improved cylinder) let you match pattern and pellet placement to your decoy spread and shooting distance. The chrome-plated chamber and bore resist the corrosion that goes with wet-weather hunting. Sling swivel studs are already threaded—mount your favorite carry rig and head to the boat.

Yes. The SX4 LH has a 3.5-inch chamber and comes equipped with an Inflex Technology recoil pad designed to manage the recoil and energy of 3.5-inch magnum loads.

The shotgun includes three Invector-Plus choke tubes, a TRUGLO fiber-optic sight mounted on the ventilated rib, length-of-pull spacers, and sling swivel studs. The fiber-optic sight is factory-installed; the swivels are threaded and ready for a sling or carrying system.
