Winchester SX4 Semi-Auto Shotgun 20ga mag 28"

There would be no point to the new SX4 if it did not take function, handling and ergonomics 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. Read More
