The SIG Sauer P320 FLUX is a next-generation take on the modular P320 platform, engineered for competition, duty, and premium defensive carry. With a 5.5" performance barrel, optics-ready slide, and a package that includes four magazines, the FLUX blends long-range sight radius, improved muzzle control, and real-world capacity. Built on SIG's proven modular chassis, it offers exceptional ergonomics, soft recoil impulse management, and the durability shooters demand. The P320 FLUX elevates the platform with a longer 5.5" barrel for enhanced velocity and sight picture while remaining balanced and controllable for follow-up shots. The optics-ready slide accepts popular micro-red dots for instant target acquisition, and the included four magazines mean you're range-ready out of the box. With modularity at its core, the FLUX accepts P320 grip modules and offers configurable controls and ergonomics to suit a wide range of shooters and mission sets.
