The Winchester SX4 Compact is a semi-automatic 20 gauge shotgun designed in a shortened configuration for smaller or lighter shooters. It pairs a 24-inch barrel with a 3-inch chamber and a black synthetic stock for a balance of handling and durability. The Compact model retains the SX4’s gas systems and ergonomic improvements while offering a reduced length of pull for a more natural shoulder mount.
