SIG Sauer P320 AXG Legion 9mm Carry, 3.9 inch Barrel, Legion Gray Cerakote, Optics-Cut Slide with Integrated Two-Port Expansion Chamber, Custom Slide Charging Handle
This SIG Sauer P320-AXG Legion stands out with its AXG aluminum-alloy grip module, Legion Gray Cerakote finish, and a slide that combines an optics cut and a slide-integrated two-port expansion chamber/compensator. It has been customized with a bolt-on slide charging handle in place of the front sight, while retaining a rear sight. The 3.9 inch barrel, modular P320 FCU architecture, and included 21- and 17-round steel magazines make this a feature-rich Legion-series pistol.
The AXG grip module features an extended beavertail, an undercut trigger guard, textured grip panels with Legion chevrons, and a flared removable-style magwell. The slide wears Legion Gray Cerakote with front and rear cocking serrations, a Legion chevron, and a two-screw cover plate over the optics cut. A Picatinny accessory rail with three slots is machined into the dust cover.
The front sight was swapped for a charging handle, providing a bolt-on slide charging handle at the muzzle end. A rear sight remains installed, and the pistol is configured as rear sight only.
This striker-fired P320 variant uses a flat, skeletonized trigger and the modular P320 FCU architecture. Capacity is 21+1 with the extended magazine, and a standard-length 17-round magazine is also included. Both magazines are steel P320 pattern.

The AXG aluminum-alloy frame is finished in Legion Gray Cerakote to match the slide, creating a cohesive Legion appearance. The removable-style flared magwell supports fast reloads, and the undercut trigger guard helps achieve a higher grip on the pistol.
The slide’s integrated two-port expansion chamber/compensator, front and rear serrations, and Legion branding are signature Legion-series touches. The optics cut is covered by a two-screw plate when not in use.
