Winchester Guns Sx4 Wgun 511252292 Sx4 Lh 12-3.5 28 Blk

The Winchester SX4 Left-Hand 12-gauge shotgun is built for the southpaw shooter who refuses to compromise on quality or handling. This left-hand semi-automatic shotgun pairs Winchester's proven gas-operated reliability with ergonomic controls and sight geometry tailored specifically for left-handed shooters—no adaptations, no workarounds. The SX4 follows Winchester's legendary Super X3 lineage, applying decades of autoloading shotgun expertise to a platform designed from the ground up for how left-handed hunters and sport shooters actually mount and operate a gun.

Built on an aluminum-alloy receiver with a non-glare matte black finish, the SX4 wears a all-black synthetic stock and forearm that work equally well in brush or open country without catching light or spooking game. Winchester's Active Valve gas system handles the full range of 12-gauge loads—from light 2¾-inch shells to heavy 3½-inch magnums—keeping cycling reliable whether you're shooting clay, upland birds, or waterfowl. The ventilated rib and TRUGLO fiber-optic front sight give you a clean sight picture in variable light conditions, while the Inflex recoil pad absorbs the sting of those heavier loads.

Practical details matter in the field: the SX4's larger cocking handle, oversized bolt release, and reversible safety button speed up operation in cold or wet conditions when your hands are numb or gloved. The slim-profile grip and textured forearm grip panels are contoured for comfort and control without gloves, and length-of-pull spacers let you dial in fit for your frame. Three Invector-Plus choke tubes (including Full, Modified, and Improved Cylinder) ship with the gun, covering common hunting and sport-shooting scenarios.

If you've never shot a true left-hand shotgun—or have settled for right-hand ergonomics your whole shooting life—the SX4 is worth handling. This is a serious hunting and sport-shooting tool, not a compromise.

Frequently Asked Questions

Is this shotgun truly left-hand, or is it just a right-hand gun with reversible controls?

The SX4 is purpose-built as a left-hand shotgun from the receiver up. The action, safety, bolt release, and cocking handle are all positioned and oriented for left-hand operation and ergonomics—not adapted from a right-hand design.

What loads does the SX4 chamber and cycle?

The SX4 is chambered for both 2¾-inch and 3½-inch 12-gauge shells. The Active Valve gas system is designed to cycle the full range of loads between those lengths reliably.

What choke tubes come with the gun?

Three Invector-Plus choke tubes are supplied with the SX4. These are removable and allow you to change the shot pattern for different game and shooting situations.

Can I adjust the length of pull?

Yes. The SX4 comes with length-of-pull spacers that let you customize the fit of the stock to your frame and shooting style.
