SIG Sauer P320 AXG Legion 3.9″ RX 10+1 9mm Pistol with Romeo1Pro Optic

The SIG Sauer P320 AXG Legion RX is the pinnacle of performance for the serious shooter. Built on the legendary P320 platform, this compact powerhouse features a 3.9″ barrel chambered in 9mm with a 10+1 capacity, making it a top choice for competition, duty carry, and advanced home defense.

At the heart of the AXG Legion is an aluminum alloy frame with an ergonomic metal grip module — replacing the standard polymer — for enhanced balance, a more natural point of aim, and a premium in-hand feel that sets it apart from the rest of the P320 lineup. Legion Series pistols are refined to exacting standards, featuring a tuned action, enhanced controls, and proprietary Legion Gray Cerakote finish that delivers both durability and a commanding look.

The “RX” designation means this pistol ships optics-ready with a pre-installed SIG Romeo1Pro red dot sight, giving you a fast, accurate sight picture right out of the box — no adapter plates or additional milling required. The Romeo1Pro is built tough, with full waterproofing and a wide field of view perfectly matched to the P320 platform.

Additional Legion-grade features include a flat trigger with an enhanced pull, extended beavertail, aggressive front strap texturing, and front and rear cocking serrations for positive slide manipulation under any conditions.
