Sig Sauer P320 AXG Legion RX 9mm 3.9" Barrel 10/21 Round Capacity$1,649.99
Availability: In Stock
The Sig Sauer P320 AXG Legion 9mm is a duty-grade striker-fired pistol built for shooters who demand reliability, control, and a refined shooting experience. This full-size XSeries platform combines Sig's modular P320 architecture with a proprietary all-metal grip module and a pair of recoil-reduction features that set it apart from the standard lineup. The 3.9-inch barrel strikes a balance between velocity and practical carry ergonomics, while the Legion Gray Cerakote finish and custom Hogue G10 grips give it a purposeful, professional appearance.
At the heart of the AXG Legion is its aluminum grip module—noticeably heavier and more solid underhand than polymer alternatives—paired with a two-port slide-integrated expansion chamber designed to reduce felt recoil. The result is a 9mm that tracks faster and recovers smoother than you'd expect from a compact-ish pistol. The trigger is Sig's flat, skeletonized XSeries design, which breaks cleanly and resets positively without excess takeup. Sig includes three 10-round steel magazines (two more are sold separately), an M1913 accessory rail, and X-Ray3 day/night sights that illuminate in low light while remaining visible in daylight without a battery.
The optic-ready slide hosts aggressive front and rear serrations for reliable grip during racking and malfunction clearance. Sig engineered the mounting footprint to accept common micro red dots—SIG ROMEO1Pro and ROMEO2, Deltapoint Pro, and Trijicon RMR—so you can set up a duty or competition-ready gun without guesswork. This is a serious pistol for shooters who want modern features, metal construction, and Sig's reputation without the guesswork of aftermarket assembly. The 36.1-ounce weight delivers a planted, stable platform, especially valuable in defensive or high-round-count range sessions.
