The Winchester SX4 is a proven semi-automatic shotgun built for hunters and sport shooters who demand reliability without compromise. This 12-gauge semi-auto features a 28-inch barrel chambered for 3.5-inch magnum loads, giving you the flexibility to handle everything from waterfowl to upland game without swapping guns. The matte black receiver and barrel keep glint out of the field, while the composite stock and foregrip reduce weight without sacrificing durability—at 7 pounds, it's light enough for a full day afield but substantial enough to manage recoil cleanly.
Winchester engineered the SX4 with a chrome-plated chamber and bore for corrosion resistance in wet conditions, and the Inflex 1 recoil pad with a hard heel insert tames felt recoil so you can stay focused on your shots. The fiber optic front sight cuts through low light, and the textured grip panels give you a secure hold even with wet or gloved hands. Straight from the box, you get three Invector-Plus flush chokes—Full, Modified, and Improved Cylinder—letting you dial in the right pattern for your hunting situation, plus a flat choke wrench to swap them in the field.
With a 4-round magazine capacity and an overall length of 49 inches, the SX4 balances maneuverability in brush with the sight radius you need for precision. The 14.25-inch length of pull suits most shooters comfortably, and the aluminum alloy receiver keeps the gun nimble. Whether you're working a duck blind at dawn or hunting pheasant over a pointer, the Winchester SX4 handles the job with the straightforward, no-nonsense performance hunters have relied on for generations.

Yes. The SX4 is chambered for 3.5-inch shells, so it will cycle both standard 2.75-inch and 3.5-inch magnum loads. This flexibility is particularly valuable for waterfowl hunters who may want extra velocity and shot capacity in a single gun.
The Winchester SX4 has a 14.25-inch length of pull, which is the distance from the trigger to the center of the recoil pad. This is a standard adult dimension and suits most shooters comfortably; if you're exceptionally tall or short, you may want to handle one in a store to confirm fit before purchase.
Yes. The chrome-plated chamber and bore resist corrosion from wet conditions and steel shot, and the 3.5-inch chamber accommodates the heavier loads waterfowl hunters typically use. The composite stock is durable in harsh field conditions, and the semi-automatic action reduces felt recoil during long hunting sessions.
