The AXG alloy grip module delivers a metal-frame feel, complemented by G10 chevron grip panels and a removable flared metal magwell. The Legion Gray Cerakote on both frame and slide provides a uniform, purpose-built finish.
The stainless steel slide incorporates an integrated two-port compensator machined directly into the top of the slide. The front sight sits behind the ports to maintain a clear sight picture while the 3.1 in barrel preserves compact dimensions.
The slide is optics-ready with a two-screw cover plate, giving you the option to add a compatible micro red dot. Out of the box, SIG X-RAY3 day/night sights are installed, with a green dot front and a black rear notch.
This striker-fired pistol uses a flat-faced trigger and includes a three-slot Picatinny accessory rail for lights or lasers. Capacity is 17+1 with the included 17-round magazines.
Key identifiers include the Legion series configuration, manufacturer part number 365AXGCA-9-LEGION, and USA manufacture. The package reflects the AXG Legion setup with its dedicated cases and Legion challenge coin.
