The SIG SAUER LEGION has joined forces with industry innovator FLUX Defense to create the SIG / FLUX factory built P320-FLUX LEGION collaboration. The P320-FLUX LEGION is a complete SIG Factory build using a P320 Fire Control Unit with a LEGION skeletonized trigger, a full-size LEGION Gray slide with integrated compensator housed in the LEGION Gray FLUX Defense chassis with rapid-deploying Stabilizing Brace.
