The Flux Defense Raider chassis transforms the P320 with practical features: a forward spare-mag Speedload system, a right-side reciprocating charging handle linked to the slide, a top optic mounting block, and a rear telescoping pistol brace with a backup irons block. Slide-mounted iron sights are retained, including a raised front sight with a green dot for fast alignment.
An installed 5.75 in steel threaded barrel with a square-profile thread protector supports suppressed setups and accessory compatibility. The striker-fired, locked-breech, tilting-barrel action delivers the familiar P320 operating system in a chassis designed for control and speed.
The included Holosun HS403B offers a 2 MOA LED red dot with 1x magnification for a clear aiming point, and the Nightstick compact weapon light mounts to the rail for illumination. The chassis provides rail space and an elevated optic position via the top mounting block.
This setup ships with three 21-round and two 17-round factory magazines, the original SIG OEM unthreaded P320 barrel (part no. 2472-02), and an OEM P320 X-Series full-size grip module, all in a SIG Sauer factory hard case. Country of origin is the USA, and the serial number is visible through the chassis window and matches the packaging label.
