The Sig P320 Flux 9mm blends the P320 series modular, striker-fired platform with a Flux chassis designed for modern duty, competition, and defensive carry, featuring a 5.5-inch 1/2x28 threaded stainless steel barrel and Nitron-finished slide for suppressed shooting and long-range 9mm accuracy. Its Rapid Deploying Stabilizing Brace and compact 10.9-inch collapsed length make it an ideal choice for close-quarters defense, carbine-style range work, or competition stages where sledged follow-up shots matter, while the non-reciprocating Picatinny optic mounting system and XRAY 3 day/night sights deliver fast, consistent sight picture for sighted and red-dot setups. Ambidextrous dual magazine release and integrated flared magwell speed reloads under pressure, the black polymer Flux chassis provides ergonomic control and durability, and the XSeries flat trigger keeps striker-fired reset and pull consistent for faster splits. This model accepts steel magazines and includes multiple capacity options for extended practice sessions and high-round drills; be aware an FFL transfer is required. With a 6-inch sight radius, 1.6-inch width and a balanced 49.2 oz weight with magazine, the P320 Flux 9mm is a versatile platform for shooters who demand adaptability and performance.
