The SX4 Compact concentrates the SX4’s operating features into a shorter package that maintains the same functional systems: a reliable gas-operated semi-automatic action, a modern fiber-optic sighting aid, and an Inflex pad to reduce shooter fatigue. Its walnut stock and compact geometry make it easy to carry and point for upland walks or when moving through a sporting clays course. For shooters who need a scaled-down, feature-rich autoloading 20 Gauge, this model balances handling and proven SX4 technologies.
