Sig Sauer P320 AXG Legion 9mm Compensated Striker-Fired Pistol | 3.9" Barrel | 17+1 | Night Sights
The P320 AXG Legion merges the modular P320 platform with the Legion series’ performance upgrades. A factory-milled slide-integrated two-port compensator keeps the overall length of a full-size slide while noticeably reducing muzzle rise. The AXG alloy grip module adds weight for steadier tracking, and the Legion-gray Cerakote finish gives the pistol a durable, uniform appearance. Generous front and rear serrations, an optics-ready cut, and X-Ray3 tritium night sights round out a package aimed at shooters who want competition-grade control in a duty-length firearm.

The slide’s built-in, two-port compensator vents gas upward, helping keep the muzzle flat and allowing split-time reductions without extending overall length. Because it is machined directly into the slide, there are no timing issues or added parts to loosen over time.
The AXG (Alloy XSeries Grip) module features aluminum sides, checkered grip panels, and an extended, removable flared aluminum magwell for faster reloads and improved recoil control. Its added mass over polymer frames contributes to softer perceived recoil.
SIG’s flat-faced, skeletonized trigger delivers a crisp break and short reset, giving the shooter a consistent, controllable press. Paired with the striker-fired action, it provides familiar P320 ergonomics with an upgraded feel.
The Legion-gray Cerakote finish coats both the slide and frame for abrasion and corrosion resistance. Front and rear cocking serrations, plus an optics-ready cut with cover plate, allow easy manipulation and straightforward mounting of red-dot sights.
Factory X-Ray3 night sights—green-ring tritium front and two-dot tritium rear—offer a bright aiming reference in all lighting. Owners also gain access to the SIG Legion program for branded gear and exclusive benefits.
