Sig Sauer P365 FLUX 9mm Pistol Brace Chassis with Romeo-X Compact Optic 6" Barrel - 21 Rd

The SIG P365‑FLUX redefines what a compact defensive platform can be—combining the concealability of a handgun with the stability, speed, and capability of a PCC‑style system. Built around the proven P365 fire control unit and enhanced with the FLUX chassis, this compact PDW delivers rapid deployment, exceptional control, and unmatched versatility in a package designed for real‑world performance.

A spring‑deploying brace allows instant stabilization, while the integrated muzzle shroud and extended 6" barrel improve recoil control and accuracy. The front Picatinny rail supports lights, lasers, or mission‑specific accessories, and ambidextrous controls—including dual magazine releases—ensure intuitive operation for any shooter. Paired with SIG’s XRAY3 Day/Night sights and compatibility with high‑capacity 17‑ and 25‑round magazines, the P365‑FLUX offers a powerful, compact solution for defense, duty, or discreet carry.

Whether you need a fast‑handling PDW for home protection or a compact platform with carbine‑like stability, the P365‑FLUX delivers a unique blend of mobility, firepower, and innovation.
