The Winchester SX4 (Winchester part no. 511252292) is a 12 gauge semi-automatic shotgun built in a full-size left-hand configuration for hunters who need controls that fall naturally to the off-hand shooter. It follows Winchester’s Super X3 Black Shadow with larger, easier-to-operate controls and a redesigned grip area for better comfort and pointability in damp or cold conditions. A matte black, non-glare finish covers the 28-inch barrel and receiver so it won’t spook game on the flush. Chambered with a 3½-inch chamber and fed by a 4-round magazine, it’s ready for everything from dove loads to heavy waterfowl magnums.
