Sig Sauer P320-FLUX Legion 9mm Compact Pistol with 3.9" Barrel, Integrated Compensator & Two 30-Round Magazines
The P320-FLUX Legion pairs Sig Sauer’s proven modular P320 fire-control unit with FLUX Defense’s rapid-deploy brace system, delivering a compact 9 mm platform that handles like a carbine. Factory-cut for optics, finished in Legion Gray Cerakote, and fitted with an integrated slide compensator, this striker-fired pistol brings Legion-series refinements—such as the skeletonized trigger and X-RAY 3 day/night sights—to a 30-round, brace-equipped package released through Sig’s FLUX partnership in June 2024.

Developed under the Sig Sauer–FLUX Defense collaboration, this Legion variant features a non-reciprocating top Picatinny rail over the ejection port, allowing secure mounting of mini red-dot optics without adding slide mass.
The integrated compensator is cut directly into the Legion-gray slide, venting gases upward to reduce muzzle rise and keep rapid strings on target—especially valuable when running 30-round magazines.
Dual magazine-release controls (standard button and paddle) let the shooter choose their preferred method, while the ambidextrous manual safety, striker safety, and disconnect provide layered protection without compromising the P320’s clean trigger break.
The polymer FLUX brace telescopes for transport, locks solidly when deployed, and carries a spare magazine inboard for immediate reloads—turning this compact 9 mm into a highly adaptable personal-defense tool.
