The Winchester SX4 Left-Hand is a gas-operated semi-automatic shotgun purpose-built for southpaw shooters who demand reliability without compromise. This 12-gauge autoloader delivers smooth, soft-shooting performance through Winchester's Active Valve gas system, while thoughtful left-hand ergonomics—including a reversible safety button and enlarged bolt release—make quick sight pictures and transitions natural. With a 26-inch barrel, 3.5-inch chamber, and 3+1 capacity, it's equally at home in the duck blind, the upland field, or on clay targets.
The SX4 Left-Hand wears a Cerakote Flat Dark Earth (FDE) finish on its lightweight aluminum alloy receiver and barrel, paired with a composite stock finished in Realtree Max-7 camouflage. The chrome-plated chamber and bore resist corrosion and wear, while the ventilated rib supports a TRUGLO fiber-optic front sight for fast target acquisition in low light. Winchester's Inflex Technology recoil pad absorbs punishment so you stay focused downrange, and length-of-pull spacers let you dial in the fit to your frame.
Out of the box, you get three Invector-Plus choke tubes (Full, Modified, Improved Cylinder) to tailor patterns for your hunting or sport-shooting scenario, plus sling swivel studs for secure carry in the field. Left-handed shotgun shooters have long made do with ambidextrous-only or right-handed ergonomics; this Winchester respects that you need controls that work the way you shoot.
