Product Overview

The Sig Sauer P320AXG Legion 9mm pistol brings duty-proven engineering to a full-size striker-fired platform designed for shooters who demand control and reliability. Built on the legendary P320 system, this Legion variant pairs an all-metal AXG grip module in Legion Gray with a slide featuring a patent-pending integrated expansion chamber that reduces felt recoil—a meaningful upgrade for rapid fire and follow-up shots. At 36.1 ounces with a 3.90" barrel, it's substantial enough to manage 9mm recoil while remaining practical for serious use, whether at the range, in competition, or for personal defense.

The P320AXG Legion is engineered for fast, intuitive manipulation. Aggressive front and rear slide serrations bite your thumb on every press. The optic-ready slide accepts Sig Sauer ROMEO1Pro and ROMEO2 red dots, as well as Deltapoint Pro and Trijicon RMR optics—future-proofing your setup. Inside the grip, custom Hogue G10 panels provide confident purchase, while an extended magwell smooths reloads under pressure. The XSeries flat skeletonized trigger breaks cleanly and allows you to feel exactly what the gun is doing. X-Ray3 day/night sights ship ready to go, and the aluminum grip module doesn't add bulk while the stainless steel slide and fire control unit withstand hard use.

Three 21-round steel magazines come standard, giving you real capacity off the shelf. The M1913 accessory rail opens options for lights and lasers. This is a serious pistol for serious shooters—built to Legion standards, which have meant premium performance and attention to detail since Sig introduced the line.
