Overview

The Flux Raider 365 Ultralight brings PDW capability to SIG's micro-compact platform. Converting the already-capable P365 into a stabilized chassis, the Raider 365 Ultralight creates one of the smallest PDW-style platforms available. The spring-loaded brace or stock system deploys quickly while maintaining a remarkably compact footprint.

The P365 Raider requires 17-round minimum magazines (compatible with 17, 21, and 25-round P365 mags only - NOT compatible with 10-15 round magazines). Flux recommends XL-length or longer slides and warns against standard 3.1-inch P365 slides and XMacro comp / AXG Legion slides. The integrated dual magazine system can hold up to 50 rounds on board, and the chassis is sized for compact lights and accessory mounting. The chassis adds enough control improvement to make fast, accurate shooting significantly easier.

For P365 owners who want maximum capability from their micro-compact, the Raider transforms the platform without requiring a separate firearm purchase. The P365's existing magazines, optic, and fire control group transfer directly to the chassis. This is the ultimate expression of what the P365 platform can become.
