Product Description

    Sig Sauer P320-FLUX TACOPS TB 9mm, FLUX Raider Chassis, 5.5 in Threaded Barrel, 30+1, Factory Case, 4 Mags

    This factory Sig Sauer P320-FLUX TACOPS TB pairs the proven P320 system with the FLUX Defense Raider chassis and a 5.5 in threaded barrel. It is a recent U.S.-made release, model code 320FLUX-9-TACOPS-TB, and comes with two 30-round and two 21-round factory steel magazines, a knurled thread protector, and the original SIG SAUER hard case.

    The FLUX Raider chassis provides a spring-assisted telescoping rear arm support with dual metal guide rods, an integrated spare-magazine well, textured grip panels, and molded backup iron sights. A short rear top Picatinny segment and a forward accessory rail are built into the chassis for mounting as needed.

    Sight picture is straightforward and durable, using a green dot front sight and a rear notch integrated into the chassis backup irons. The striker-fired action and polymer frame keep handling familiar for P320 users while delivering the TACOPS feature set in the FLUX configuration.

    The 5.5 in threaded barrel ships with a knurled protector installed. Capacity is 30+1 with the included extended magazines, and the package adds depth with two additional 21-round factory magazines. The factory mfg part number 320FLUX-9-TACOPS-TB provides easy verification of this exact configuration.
