Winchester SX4 Field 26" 12ga Shotgun 3" Semi-Auto Satin - 511210391$966.38
Availability: In Stock
The Winchester SX4 Cantilever Buck is a 12-gauge semi-automatic shotgun purpose-built for slug hunting on deer. Unlike a general-purpose waterfowl gun pressed into service for big-game season, this shotgun is engineered from the ground up with the rifled barrel, sight plane, and ergonomics that serious deer hunters need. The 22-inch rifled barrel optimizes accuracy with 2¾" and 3" sabots and slugs, while the Weaver-style cantilever rail makes scope or electronic sight mounting straightforward. At 43 inches overall and 7 lbs 8 oz, it handles well through brush and maintains control during the quick moments that matter.
The SX4's semi-auto action uses Winchester's self-adjusting active valve system, which reliably cycles a wide range of loads while keeping recoil manageable—critical when you're wearing layers in November and need to stay steady for follow-up shots. The synthetic stock with textured grip surfaces won't slip in cold, wet conditions, and the non-glare matte black finish won't spook wary bucks. An ambidextrous crossbolt safety lets both right- and left-hand shooters access it naturally, while the drop-out trigger group makes field cleaning easy on a hunt.
Fit matters. The SX4 Cantilever Buck includes length-of-pull spacers so you can dial in the stock to your frame—whether you're a smaller hunter or running a winter coat. The Inflex recoil pad is angled to send felt recoil downward and away from your cheek, reducing flinch and fatigue during a long day in a blind or hiking ridge country. It comes with a TruGlo fiber-optic front sight and adjustable rear sight for quick, low-light aiming when you don't have a scope mounted.
If you've been trying to hunt deer with a gun built for ducks, the Winchester SX4 Cantilever Buck is the right tool that actually fits the job.
