Flux Defense is back at it, taking the already wildly popular SIG P365 platform and turning it into something that punches way above its weight class. The Raider 365 Ultralight isn’t just another chassis system; it’s a full-blown micro PDW concept shrunk down to something you can actually carry.
Built around a high-strength polymer chassis, the Ultralight trims serious weight without sacrificing capability. At just 8.7 ounces, it’s absurdly light, yet still delivers the kind of stability and control you’d expect from a much larger platform.
And yes, this thing is still concealable. Folded up, it’s compact enough to ride IWB, OWB, or off-body without feeling like you strapped a subgun to your belt.

Speed, Capacity & Control
Here’s where things get spicy. The Raider 365 Ultralight effectively doubles your onboard capacity thanks to its integrated spare mag system and supports extended P365 magazines up to 25 rounds.
Flux also built in a patented “Speedload” system, meaning reloads are faster than your average pistol and arguably faster than some PCCs. Pair that with a spring-loaded, push-button deployable brace, and you’ve got a platform that transitions from concealed carry to stabilized shooter in under a second.

What does it mean? More hits, faster splits, better control.
Small Package, Big Performance
Despite its size, the Ultralight isn’t just about convenience, it’s about performance. Flux claims increased accuracy, improved recoil control, and even higher velocity compared to running a standalone handgun.
Want to stretch it out even further? There’s room for suppressors and optional longer barrels, pushing this setup into legitimate “truck gun” or “bag gun” territory.

And in true Ballistic fashion, let’s call it what it is: this is basically an MP5K’s minimalist cousin; 3 inches shorter and dramatically lighter, but still ready to work.
The CQB Evolution
The Raider 365 Ultralight is compact enough to stash in tight spaces but deploys fast enough to matter when things go sideways.

It’s not a firearm, it’s a chassis, but what it enables is a whole new category of concealed, high-performance defensive setups.
Bottom line? If you’ve ever wanted PDW performance without lugging around a brick, the Raider 365 Ultralight might be the most fun, and functional, you can have with a P365.
