The P320-FLUX Legion is a factory build that integrates SIG Sauer's striker-fired P320 fire control with Flux Defense's Raider polymer chassis. The chassis incorporates the front SPEEDLOAD SYSTEM spare-magazine carrier and dual-magazine release logic for streamlined reloads and intuitive control.
Its compensated, ported 3.9 in slide in Legion Gray tempers muzzle rise while maintaining compact slide length. A day/night front sight provides a clear sight picture.
A non-reciprocating rear Picatinny optic rail and a forward accessory rail expand mounting options. The spring-loaded, telescoping, rapid-deploy brace adds stability while keeping overall length to 10.9 in collapsed (approximately 18 in extended). Height is 6.1 in, width is 1.6 in, and listed weight is 49.2 oz.
This Legion-series model features an ambidextrous manual safety and a flat-faced, skeletonized Legion trigger. Capacity is 30+1 with the included extended magazines. The model/SKU is 320FLUX-9-LEGION, announced in June 2024 and made in the United States.
