Two years ago, the Winchester shooter Raniero Testa and his SX4 beat a world speed record. Holding in your hands the fastest semi-auto shotgun on the market gives you a decisive advantage during your small game hunts. Compared to the SX3, the SX4 is 100 grams lighter with a fine pistol stock and redesigned chequering. The centre of gravity has been moved forward for better swing through, and Winchester says it has faster cycling too. It comes with 26,28 or 30-inch back bored barrels, three Invector Plus chokes, and a fibre-optic sight with a long, top-mounted front sight. Quadra-Vent gas ports reduce felt recoil. The SX4 is available in wooden field version, as well as composite and camo designs.
