Flux Defense Flux Defense Raider 365 Blk Pdw

The Flux Defense Raider 365 PDW chassis transforms your SIG Sauer P365 into a compact personal defense weapon that splits the difference between handgun and subgun. This is not a firearm itself—it's a chassis upgrade that accepts your P365 slide and barrel to create a remarkably small, controllable defensive tool. If you're looking for subgun-level accuracy and handling in a package that still conceals like a pistol, the Raider 365 delivers exactly that.

Built from duty-grade 7075 aluminum and S7 steel with Type 3 hard anodizing, the chassis weighs just 12.6 ounces and collapses to 9.75" x 4" x 1.375", making it genuinely concealable—even smaller than a TP9 when a suppressor is mounted. Extended, it stretches to 18.5" but still offers three to four points of contact for MP5-level control and accuracy. You get the speed of a handgun draw with the handling of a short-barreled rifle, all without the bulk that usually comes with that performance jump.

The system includes a patented Speedload mechanism faster than traditional magazine changes, a built-in C-clamp shroud for a secure grip, and an optional fixed red dot mount. You can run up to a 6" barrel (yielding velocity comparable to an MP5K) and stack 50 rounds on the gun with optional magazine extensions. Use factory P365 safety levers, and benefit from construction that's roughly 70% lighter than an MPX or MP5.
