Winchester SX4 26" 12ga Shotgun 3.5" Semi-Auto Matte - 511205291

The Winchester SX4 26" 12-gauge semi-auto shotgun is a versatile, gas-operated workhorse built for hunters and sport shooters who need reliable performance in the field. With its 3.5" chamber, aluminum-alloy receiver, and matte finish throughout, the SX4 handles everything from waterfowl and upland game to clay courses with the same no-fuss dependability Winchester shooters have counted on for generations. The 26" barrel is handy enough for thick cover and fast target acquisition, while the inverted fiber-optic front sight cuts through low-light conditions—ideal for dawn and dusk hunting when birds are moving.

Winchester engineered the SX4 around real-world recoil management. The Inflex 1 recoil pad with hard heel insert absorbs punishment so you stay focused and on target through a full morning of shooting. At 6 lbs 12 oz, it balances weight and swing speed; light enough not to tire your arms, substantial enough to track smoothly. The composite stock with textured grip panels grips securely even with cold, wet hands—a detail that matters when you're slung up in a blind.

The gun ships with three Invector-Plus flush chokes (Full, Modified, and Improved Cylinder) so you can match patterns to your distance and game without buying aftermarket tubes. The tubular magazine holds four rounds, and the chromed chamber and bore resist corrosion from moisture and powder residue, extending the life of a gun that might spend years in trucks and duck blinds. The supplied flat wrench makes choke changes field-friendly, and quick-detach sling studs get you mounted and ready in seconds.

Whether you hunt over water, work a pointing dog through grass, or break clays on weekends, the SX4 delivers the accuracy, handling, and durability that make a shotgun disappear in your hands.
