NEWINGTON, N.H., (June 25, 2024) – The SIG SAUER® LEGION® has joined forces with industry innovator FLUX Defense to create the SIG / FLUX factory built P320-FLUX LEGION collaboration.  Designed with feedback from the Special Operations Community, the P320-FLUX LEGION delivers on innovation and enhancements that have become the trademark features of SIG SAUER LEGION Series designs.

“The P320-FLUX LEGION takes a 9mm handgun, using the SIG SAUER P320 Fire Control Unit, and transforms it into an easily concealed PCC style platform, with the stability of a carbine and loads of LEGION upgrades to bring more speed, maneuverability, and control to conceal carry,” said Robby Johnson, Chief Marketing Officer, SIG SAUER, Inc.  “This build has a long list of features including a single-finger fast deploying spring brace for rapid deployment, 30-round capacity, an integrated compensator in the custom LEGION slide, and a dual-mag release system to get you started.  Add to that the endless amounts of customization that can be achieved with the front and rear picatinny mounts and an ambidextrous safety we are sure that the P320-FLUX LEGION is destined to be a LEGION fan favorite.”

The P320-FLUX LEGION is a complete SIG Factory build using a P320 Fire Control Unit (FCU) 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.  Build features include XRAY3 Day/night sights, an ambidextrous dual magazine release system, front picatinny mount, rear non-reciprocating picatinny optic mount, an integrated flared magwell, and ambidextrous safety.  The full build ships fully assembled with (2) extended 30-round P320 magazines.

“A collaboration of this scale is an exciting first for us, but given the reputation SIG has for quality, innovation and disrupting the industry, which FLUX Defense also shares, this partnership came naturally to everyone,” added Arrius Sorbonne, FLUX Defense Co-Owner.
