Winchester Guns Sx4 Wgun 511283292 Sx4 Lh 12-3.5 28 Shdwgr

The Winchester SX4 left-hand 12-gauge autoloader is built for serious waterfowlers who need a shotgun designed from the ground up for southpaws. This left-handed model mirrors the proven platform that dominates the marsh, giving left-handed shooters access to the same gas-operated reliability and speed as their right-handed counterparts. The 28-inch barrel and 3.5-inch chamber handle the full range of waterfowl loads, while the Mossy Oak Shadow Grass Habitat camo provides effective concealment in reed beds and standing grass common to salt marshes and inland wetlands.

At the heart of the SX4 is Winchester's Active Valve gas operating system—the same technology that powered the trusted SX3 and SX2 platforms. This proven action cycles reliably in cold, wet conditions and handles everything from light target loads to heavy magnum shells without missing a beat. The aluminum alloy receiver is finished in full-coverage Mossy Oak Shadow Grass Habitat camo, and the chrome-plated barrel with ventilated rib balances durability with weight savings.

Winchester engineered the SX4 left-hand specifically for faster handling. Larger cocking handle, bolt release, and reversible safety button speed up operation even with heavy gloves on. The TRUGLO fiber-optic sight makes target acquisition quick in low light, and the wider trigger guard opening accommodates gloved fingers without fumbling. Included three Invector-Plus choke tubes let you dial in the right constriction for your conditions, and the Inflex recoil pad paired with length-of-pull spacers helps absorb recoil and fit your frame correctly.

Frequently Asked Questions

Is this shotgun really designed for left-handed shooters?

Yes. The SX4 left-hand model is a true mirror image of the standard SX4, with the cocking handle, bolt release, safety button, and ejection port all positioned for southpaw operation. Winchester built it from the ground up for lefties, not as an afterthought.

What choke tubes come with the SX4 left-hand?

Three Invector-Plus choke tubes are included. These allow you to adjust your shot pattern for different distances and game—a practical advantage for waterfowling where conditions vary.

Will this shotgun handle heavy magnum loads?

Yes. The 3.5-inch chamber accommodates both 3-inch and 3.5-inch shells, so you can run full-power loads when needed. The Active Valve gas system is engineered to cycle reliably across the full range.

What's the deal with the larger safety and cocking handle?

Winchester designed these larger controls to speed up operation when you're wearing heavy gloves or mittens—common in early-season duck hunts and cold-weather shooting. The wider trigger guard opening serves the same purpose.
