Winchester SX4 Matte Black 12 Gauge 3in Semi Automatic Shotgun - 26in - This Super X4 follows on the heels of the most successful Winchester autoloader ever: the Super X3 Black Shadow. There would be no point to the new SX4 if it did not take function, handling and egonomics to the next level. And it does. This is a dedicated hunting machine with it's all-black exterior that is definitely non-glare to prevent spooking game. Critical functional controls are larger and easier to operate -- a real benefit in damp weather and cold conditions.
