The Raider X P320 is the next evolution of the Flux Raider platform — a premium personal defense weapon chassis system engineered for the SIG Sauer® P320, M17, and M18 family of pistols. It’s not a firearm — it’s a purpose-built chassis upgrade, born from real-world feedback from special operations units and thousands of everyday users. Stronger, lighter, faster — and ready to keep you in the fight.
