The slide features a PRO-footprint optics cut with no cover plate installed, plus an integral expansion chamber with top ports. Sights are set up with a SIG X-RAY 3 tall green-dot front and a fully adjustable rear, giving a precise iron-sight setup out of the box.
The single-action-only, hammer-fired system is built around SIG’s AX3 trigger: a flat, skeletonized, fully adjustable unit with an over-travel screw for fine tuning. An ambidextrous thumb safety and a spurred, lightened hammer round out the control suite.
The Legion-configured aluminum-alloy frame adds practical enhancements: extended beavertail, vertically serrated front strap, and a flared magwell for confident reloads. Steel grip panels carry an aggressive texture with the Legion chevron motif for secure purchase.
A full-length MIL-STD-1913 accessory rail with four slots supports light or laser placement, while the oversized sport takedown lever ("gas pedal") provides a dedicated index point and added control. X-FIVE and Legion markings are present throughout.
