The Sig Sauer P320 FLUX Legion is a cutting-edge fusion between a full-size 9mm handgun and a personal defense weapon (PDW)-style platform. Engineered in partnership with FLUX Defense and developed with feedback from Special Operations communities, it combines the maneuverability of a pistol with the stability of a carbine, offering advanced features and modularity for professional, competitive, and home defense applications.
