SIG SAUER P365-FLUX 9mm – 6-inch Barrel, ROMEO-X Compact, FLUX Side-Folding Brace, 25+1 Capacity
This P365-FLUX pairs SIG SAUER's micro 9mm format with a 6-inch barrel and a P365 XSeries slide, adding a factory-installed ROMEO-X Compact red dot and a FLUX side-folding, spring-assisted pistol brace. It is a recent release made in the United States and ships with high-capacity factory magazines.
The 6-inch configuration is the longest factory P365 barrel, delivering a distinctive long-slide profile within the XSeries family. The pistol is striker-fired, finished in black throughout, and configured for 9mm Luger with a maximum capacity noted as 25+1.
The FLUX-branded brace is installed and features a side-folding design with a push-button deploy lever and spring-assisted action, all finished in black to match the slide and frame.
A Sig Sauer Romeo-X Optic is included: the ROMEO-X Compact red-dot sight comes installed with a 7075-aluminum housing, side-loading CR1632 battery, MOTAC motion activation, a low deck height for co-witness, and an RMSc/Compact footprint. Backup co-witness sighting references are present alongside the optic, including a green-dot front blade.
This example includes one 25-round magazine and two 17-round magazines. It ships with the SIG SAUER factory hard case and the correct manuals, along with the brace and optic installed. MFG part number is 365FLUX-9-BXR3-RXSL.
