Winchester's award-winning SX4 semi-auto line has been expanded to include a sweet-swinging 20-gauge. It’s just as fast and reliable as the 12-gauge but has been slimmed down into an ideal upland workhorse. Available models include wood and synthetic stocks, camo and matte-black finishes, 24-, 26- or 28-inch barrels and even a youth model. Weighing only 6 pounds, 10 ounces, the 20-gauge SX4 functions with the reliability the company's Active Valve gas system is known for.
