SIG Sauer P320 AXG Legion 9mm Striker-Fired Pistol | Optics-Ready, Compensated, Alloy Grip Module
The P320 AXG Legion draws on SIG Sauer’s elite Legion program to deliver a factory-compensated, optics-ready pistol built around a hard-coat-anodized aluminum AXG grip module. Finished in matching Legion Gray Cerakote, it pairs a flat-face, 4.5 lb skeletonized trigger with a 4.6" barrel and slide-integrated compensator that helps keep the muzzle flat. Modular construction, premium day/night sights, and three 10-round magazines make this an immediately capable sidearm or competition foundation.

The alloy AXG grip module gives this P320 a solid, ergonomic feel with textured G10 panels and a detachable flared magwell for faster reloads. Because the serialized fire-control unit is modular, the owner can swap grip modules or calibers without a gunsmith.
A factory-milled slide accepts ROMEO1Pro/ROMEO2, Deltapoint Pro, or RMR-pattern optics without adapter plates. The slide’s front and rear serrations, plus generous ports, complement the self-indexing compensator that reduces felt recoil and muzzle rise.
SIG’s X-Ray3 day/night front sight teams with a blacked-out rear sight on the optic plate, providing a clear sight picture when no red-dot is installed. The Legion Gray Cerakote on both slide and frame offers enhanced corrosion resistance and a distinctive, low-glare appearance.
The flat-face skeletonized trigger breaks at approximately 4.5 pounds, promoting consistent, straight-to-the-rear press. Combined with the striker-fired action and fully supported 4.6" barrel, the result is a smooth, controlled shooting experience.
Legion membership perks—including exclusive gear offers and training opportunities—are available to the buyer upon registering the pistol’s serial number with SIG Sauer.
