The Winchester SX4 26" 12ga semi-automatic shotgun is a lightweight, fast-handling platform built for hunters who value quick target acquisition and reliable performance in the field. At just under 7 pounds with a 26-inch barrel and 47-inch overall length, this matte-finished workhorse balances maneuverability with shootability—ideal for upland game, waterfowl, and sport shooting where you need to move through cover or swing on crossing birds without fatigue. The composite stock and aluminum alloy receiver keep weight down while the chrome-plated chamber and bore handle 3-inch magnum loads, giving you versatility across a range of ammunition.
Winchester's gas-operated action is renowned for reliability and smooth cycling, and the SX4 backs that reputation with a 4-round tubular magazine and inverted inertia system that cycles reliably across shot sizes and velocities. The Inflex 1 recoil pad with hard heel insert tames felt recoil without adding bulk, and the textured grip panels and sling swivel studs ensure you can maintain control and attach your carry method of choice. A red fiber-optic front sight aids target pickup in low light, and the flat rib helps manage swing and sight picture.
The SX4 ships with three interchangeable Invector-Plus flush chokes—Full, Modified, and Improved Cylinder—letting you tailor pattern density for different ranges and applications without buying expensive replacement tubes. The included choke wrench makes swaps simple in the field. Matte finishes on the receiver, stock, and barrel resist glare while standing up to hard use, and the thoughtful ergonomics—14 1/4" length of pull and drop dimensions of 1 3/4" at comb and 2" at heel—support a natural cheek weld and quick aim. Whether you're hunting early season tight cover or spending a day at the clay range, the Winchester SX4 26" delivers the speed and reliability serious shotgunners demand.
