The FLUX Legion configuration integrates the P320 fire control with a FLUX Raider-type chassis. It adds a non-reciprocating rear Picatinny optic rail and the integrated forward spare-magazine carrier known as the Speedload System, keeping a second magazine at hand without adding bulk to the grip.
The slide is finished in Legion Gray and includes front and rear serrations, an optic cut with cover plate, and an integrated compensator to help manage muzzle rise. A Flux F10 charging handle is mounted on top for direct, ambidextrous access without disturbing the optic rail.
This compact, striker-fired setup retains an ambidextrous manual safety and a flat-profile trigger. The 3.9 in. barrel balances handling with velocity, while the telescoping, rapid-deploying stabilizing brace delivers quick, repeatable shoulder indexing for controlled strings.
Capacity is 30+1 with the included extended SIG steel-body magazines. The chassis and slide are matched in Legion Gray, and the model is identified by the factory part number 320FLUX-9-LEGION, with serial verified against the matching case label for straightforward confirmation.
