Flux Defense Expands the Raider 365 With New Competition and Carry Magwells
Flux Defense has once again pushed the limits of what’s possible with the SIG P365 platform, proving that modularity isn’t just a feature—it’s a foundation. The Raider 365 chassis has reimagined what a micro-compact could be, transforming Sig Sauer’s already popular P365 FCU into a compact, capable bag gun or PCC you can carry. Now, Flux continues to refine the 365 Raider with the release of their new magwell offerings—giving users tailored options for either competition or carry.
Two Magwells, Two Missions
Flux is now offering two new magwell options for the Raider 365 chassis: one tuned for competition-style performance and the other slimmed down for real-world concealed carry. The idea here isn’t just about faster reloads—it’s about intent. It’s about how you want to run your setup.
The Competition Magwell is unapologetically bold. Machined from 7075 T6 aircraft-grade aluminum and finished in black, it flares outward aggressively, channeling your mags into place with less fumbling and more speed. For those using their Raider 365 as a PCC-style bag gun or taking it to the range for drills, this magwell is the clear choice. It turns reloads into muscle memory and lends the Raider chassis a more rooted, performance-driven silhouette. There’s substance behind the design here.
But let’s not forget the Carry Magwell, because Flux didn’t. The design team knew not everyone wanted a wide, race-gun style magwell on a chassis they might be carrying under a hoodie or keeping tucked in a discreet backpack. So they built something slimmer—low profile, no unnecessary flair, just enough to guide your mag in smoothly under stress without adding bulk. It maintains the same rock-solid aluminum build, but this one’s tuned for minimalism and practicality. It’s made for real-world movement, not just setup for a bag gun.
Both magwells attach directly to the Raider 365 chassis, no gunsmithing required. Simple. Clean. Intentional.
Why It Matters
With the addition of these magwells, Flux Defense is leaning hard into what modularity should really look like. The P365 was always praised for its adaptability, but the Raider chassis elevates that into a full-blown system—and now with mission-specific magwells, you get to dictate what role your firearm plays.
Maybe you run it as a backpack companion, stowed discreetly and ready to deploy fast. Or maybe you’re training reloads on the clock, pushing performance and shaving seconds. With these two new options, you’re not stuck compromising between speed and slimness. Flux is giving end users the ability to tailor their setup down to the smallest detail.
Final Thoughts
Flux Defense continues to do what few companies dare—question what a gun can be. The Raider 365 chassis redefined the P365 as a modular defensive platform, and the addition of these magwells only deepens that commitment. Whether you’re leaning tactical or practical, competition or concealment, Flux has your setup covered.
The carry magwell is priced at $89.99, while the competition magwell retails for $99.99 MSRP. Both are available now through Flux Defense’s website.
