- →Recommended Donors: P365 XL, Macro, or Tac Ops for best performance. Avoid the shortest P365 variants.
- →Sub-Second Deployment: 0.8-second draw from concealment with SMG-like capabilities in a concealable package
The Ultralight: Polymer Takes the Stage
The Flux Raider 365 Ultralight represents the next evolution of Flux Defense's micro-PDW platform. By switching from the original metal chassis to high-strength polymer, Flux has created a system that weighs less than a standard M17 service pistol while maintaining the stabilized shooting characteristics that made the Raider platform popular.
The polymer construction also changes the shooting experience. Users report the frame disperses recoil energy differently than the metal version, resulting in what many describe as a "softer" shooting feel despite the lighter weight.

Best Donor Guns
The $499 MSRP covers only the chassis and redesigned Gen 2 holster. Users must supply their own SIG P365 fire control unit, slide, optic, and light. Flux Defense specifically recommends against using the shortest P365 slides, as they can be too snappy in this configuration.

#1 Recommended
P365 Tac Ops
Optimal barrel length and weight distribution
Great Choice
P365 XL
Extended slide and grip for better control
Great Choice
P365 X-Macro
Higher capacity with optimized ergonomics
The manual of arms remains intuitive. Magazine changes and slide manipulation can be performed without removing the weapon from the shoulder, maintaining target engagement throughout reloads.
SIG Raider 365: Complete Packages
SIG Sauer now sells complete Raider 365 systems directly, removing the need to source components separately. These packages combine the Flux chassis with SIG P365 X-Macro internals and an optimized 6-inch barrel for improved control at distance.

SIG P365-FLUX Package Tiers
- P365-FLUX$1,569.99 (2x 17-rd + 1x 25-rd mags)
- P365-FLUX TACKIT$1,719.99 (3x 17-rd + 1x 25-rd mags, light, holster)
The TACKIT package includes a FOXTROT1X weapon light, three 17-round magazines, one 25-round magazine, and an ambidextrous IWB/OWB holster. The system maintains only 1-inch thickness, allowing genuine concealed carry of what amounts to a 43-round capacity PDW (with spare magazine).

Technical Features
The brace deploys via a single-button spring-loaded mechanism with a bungee system that prevents dead hang, keeping the brace extended even if it contacts the shooter's arm during deployment.


Key Features
- Muzzle ShroudRemovable for Suppressors
- Speed Load SystemMulti-Stage Mag Release
- Optic MountSIG-Loc (RMR-SC Footprint)
- Profile Thickness1 inch
- P365 CompatibilityAll Standard Controls
The muzzle shroud helps manage blast and improve control, but can be removed to accommodate suppressors with aftermarket threaded barrels. The Speed Load magazine system uses a multi-stage button: a light press releases the front (spare) magazine, while a deep press releases both magazines simultaneously for rapid reloads.
A face indicator icon on the brace serves as a visual index to ensure the user's face remains clear of the reciprocating slide. All standard P365 controls remain functional: takedown lever, slide release, and safety.

What This Means
The Raider 365 Ultralight makes the micro-PDW concept more accessible on two fronts: the $499 polymer chassis drops the entry price significantly below the original metal version, while SIG's direct-sale complete packages eliminate the parts sourcing complexity.
The real value proposition is concealability. At 1-inch thick with the brace folded, the Raider 365 fits where a full-size pistol fits but provides stabilized shooting and significantly higher capacity. The claimed 0.8-second draw from concealment with brace deployment puts it in the same deployment speed category as a standard holstered pistol.
For existing P365 XL, Macro, or Tac Ops owners, the $499 Ultralight chassis offers an interesting upgrade path. For those starting fresh, the SIG P365-FLUX TACKIT at $1,719.99 provides a complete turnkey solution with light, magazines, and holster.
