SIG 320AXGF9LEGIONRXX10 | P320 AXG Legion 9mm | 3.9″

The SIG Sauer P320 AXG Legion is a factory-configured AXG (Alloy X Grip) pistol in Legion Gray with a 3.9-inch compensated slide and an installed ROMEO-X reflex sight. It pairs an all-metal grip module with a slide designed to reduce felt recoil and improve sight recoverability. The pistol ships with 10‑round magazines and XSeries flat skeletonized trigger that supports consistent breaks in rapid strings.

For an aftermarket optic under $1,000 that complements the ROMEO-X platform and the P320 AXG Legion, the SIG Sauer ROMEO1PRO is a direct-fit choice offering reliable performance and simple co-witnessing with the XRAY3 sights.

Typical applications for this pistol include competition shooting where fast follow-up shots and recoil management matter, and range/practice use for shooters seeking a heavy-frame, duty-grade trigger feel.
