SIG Sauer P365 FUSE 9mm with Flux Raider Chassis & ROMEO-X Red-Dot • 21+1 Micro-PDW
This factory-custom SIG Sauer P365 FUSE transforms the proven micro-compact into a fast-handling personal-defense weapon. Housed in a FLUX Defense Raider 365 aluminum PDW chassis with a side-folding skeletonized stock and topped with a factory-installed SIG ROMEO-X Compact red-dot, it delivers carbine-like stability in a 9mm package that still accepts the modular P365 fire-control unit. First-year production (case label dated January 20 2025) adds collector appeal, while the 21-round capacity keeps it practical.

What’s Included
- SIG Sauer gray plastic hard case (latch-top)
- SIG Sauer ROMEO-X Compact 3 MOA red-dot sight (factory-installed, direct-mounted)

The FLUX Raider 365 chassis converts the micro P365 into a controllable PDW. Its hard-anodized aluminum body integrates a side-folding stock with a 13.5-inch length of pull, letting the gun stow compact and deploy instantly.
A patented dual paddle-style ambidextrous magazine release speeds reloads while preserving full compatibility with standard P365 magazines—including the three high-capacity steel mags supplied here.
The factory-zeroed SIG ROMEO-X Compact red-dot delivers a crisp 3 MOA aiming point and co-witnesses with the fiber-optic front and black serrated rear sights for rapid target acquisition in any light.
Inside, the nickel-plated flat-faced trigger and striker-fired action offer a consistent, clean break. The nitride-coated carbon-steel 4.3-inch barrel, paired with a black DLC stainless-steel slide sporting front and rear serrations, ensures durability and easy manipulation.
Because the serialized fire-control unit is modular, the shooter can swap between the Raider chassis and the included P365 LXG grip module in minutes—no gunsmithing required.
