ORIGINAL RAIDER 365 and its variants. The Raider 365 is a personal defense weapon chassis system for the SIG Sauer P365 — not a firearm. Smaller than a TP9, faster than a handgun, and delivers subgun-level control in a truly concealable upgrade. Overmatch your threats with the world’s smallest PDW chassis.

The Raider 365 is the world’s smallest, fastest, and most concealable personal defense weapon chassis system, engineered specifically for the SIG Sauer P365 platform. It is not a firearm — it’s a chassis upgrade that transforms your P365 into a compact, mission-ready PDW with unmatched speed and control.

Smaller with a 4” suppressor than a TP9 without one, the Raider 365 redefines covert carry. It’s just 1 inch longer than a Glock 17 yet allows you to run a 6” barrel and gives you 3 to 4 points of contact for MP5-level accuracy — all while drawing as fast as your standard handgun.

Why? If your 9mm personal defense weapon is the size of a carbine, you’re carrying extra bulk for no benefit. This chassis delivers subgun performance in a truly concealable footprint.
