Flux Defense

Flux Defense manufactures purpose-built chassis systems that convert compact pistols into high-performance personal defense weapons. Their flagship product, the Raider 365, is engineered specifically for the SIG Sauer P365 platform.

This isn't a firearm — it's a chassis upgrade that transforms your P365 into a compact, mission-ready PDW with unmatched speed and control. The specs tell the story:

• •Smaller than a TP9 even with a 4" suppressor attached
• •Extended to 18.5" but collapses to just 9.75" for carry
• •Weight: Only 12.6 oz — 70% lighter than an MPX or MP5
• •Barrel options: Run up to 6" for increased velocity
• •Magazine capacity: Up to 50 rounds with optional extensions
• •Speed: Patented speedload system faster than any pistol or PDW

Proven in competition: Dicken Drill in 3.17 seconds from concealed draw. Bill Drill from appendix carry in 1.52 seconds.

Constructed from duty-grade 7075 Aluminum and S7 Steel with Type 3 hard anodizing. Features a built-in shroud for secure C-clamp grip, optional fixed red dot mount, and uses factory P365 safety levers. The design delivers 3 to 4 points of contact for MP5-level accuracy while maintaining true concealability.
