Sig Sauer P320 FLUX Legion 9mm | 3.9″ | 320FLUX-9-LEGION

The Sig Sauer P320 FLUX Legion is a fully modular, PCC-style 9mm platform built around the Legion gray FLUX chassis and an integrated compensated Legion slide. This configuration ships with XRAY3 day/night sights and two 30-round magazines, and is designed for fast magazine changes and stable, rapid follow-up shots. For a quality optic under $1,000 that pairs well with this platform, consider a compact red dot such as the Holosun 507K for a low-profile, robust sighting solution. Common applications include PCC competition and range training where capacity, controllability, and rapid target acquisition are priorities.
