Flux Raider 365 Ultralight: Polymer Micro-PDW at SHOT Show 2026

Flux Defense introduces the Raider 365 Ultralight at SHOT Show 2026: a polymer-framed micro-PDW chassis for the SIG P365 platform at $499 MSRP. SIG Sauer now sells complete P365-FLUX packages directly, starting at $1,569.99.

Key Takeaways

  • Ultralight Chassis: New polymer frame at $499 MSRP (includes chassis + Gen 2 holster), lighter than the original metal Raider and lighter than an M17
  • SIG Direct Sales: Complete P365-FLUX packages now available from SIG: Base ($1,569.99) and TACKIT ($1,719.99)
  • 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.

Raider 365 Ultralight Specifications

  • Frame MaterialHigh-Strength Polymer
  • MSRP (Chassis + Holster)$499
  • WeightLighter than M17
  • IncludesChassis + Gen 2 Holster
  • Brace DeploymentSpring-Loaded, Single Button
  • Draw Speed0.8 sec from concealment

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.

Frequently Asked Questions

What is the Flux Raider 365 Ultralight?
The Flux Raider 365 Ultralight is a polymer-framed micro-PDW chassis for the SIG Sauer P365 platform, debuted at SHOT Show 2026 at $499 MSRP (chassis plus Gen 2 holster). The chassis drops a P365 fire control unit into a compact, stabilized shooting platform with a single-button spring-loaded brace, sub-second deployment from concealment, and a 1-inch profile thickness that fits in the same carry spaces as a full-size pistol.
Does the Flux Raider 365 require a donor pistol?
Yes. The $499 chassis covers only the chassis and Gen 2 holster. Users must supply their own SIG P365 fire control unit, slide, optic, and light. Flux Defense specifically recommends the P365 Tac Ops as the top donor (optimal barrel length and weight distribution), followed by the P365 XL (extended slide and grip) or P365 X-Macro (higher capacity). Flux advises against using the shortest P365 slides because they run too snappy in the chassis.
How much does the complete SIG P365-FLUX package cost?
SIG Sauer sells two complete P365-FLUX packages direct. The base P365-FLUX is $1,569.99 and includes the Flux chassis with SIG P365 X-Macro internals, an optimized 6-inch barrel, two 17-round magazines, and one 25-round magazine. The P365-FLUX TACKIT is $1,719.99 and adds a FOXTROT1X weapon light, a third 17-round magazine, and an ambidextrous IWB/OWB holster.
Is the Flux Raider 365 considered a pistol or an SBR?
The Raider 365 uses a pistol brace, so it is sold as a pistol rather than a short-barreled rifle under current ATF classification. Legal status for braced pistols has shifted repeatedly, so buyers should check current federal and state regulations before purchase. The Raider 365 uses a single-button spring-loaded brace with a bungee system that prevents dead hang, keeping the brace extended even if it contacts the shooter's arm during deployment.
How fast can you draw the Flux Raider 365?
Flux Defense claims a 0.8-second draw from concealment with brace deployment. The spring-loaded single-button brace deploys to full cheek-weld in the motion of the draw, and the manual of arms preserves P365 controls (takedown lever, slide release, safety) so magazine changes and slide manipulation can be performed without removing the weapon from the shoulder. At 1-inch thick with the brace folded, it fits in the same concealment spaces as a full-size pistol.
What magazine capacity does the Flux Raider 365 support?
The Raider 365 accepts standard SIG P365 magazines, with 17-round and 25-round factory SIG magazines being the common carry options. The complete SIG P365-FLUX TACKIT package ships with three 17-round magazines and one 25-round magazine, giving a total of 76 rounds with spare mags. The chassis also includes a Speed Load multi-stage magazine release: a light press releases the front spare magazine, and a deep press releases both magazines simultaneously for rapid reloads.
Can you suppress the Flux Raider 365?
Yes. The Raider 365 Ultralight has a removable muzzle shroud that can come off to accommodate suppressors when paired with an aftermarket threaded P365 barrel. The chassis was demonstrated running suppressed at SHOT Show 2026 Range Day. The muzzle shroud otherwise stays in place to manage muzzle blast and help control the short, snappy P365 slide cycle.

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.
