Flux Defense Raider 365

The Flux Defense Raider 365 is a purpose-built chassis system that transforms a standard SIG Sauer P365 into a compact, controllable pistol platform. Designed for shooters who demand maximum performance from a subcompact carry gun, the Raider 365 integrates a stabilizing brace, an integrated magazine well, and a full-length accessory rail into a single, rigid unit. This is not a conversion kit; it is a dedicated platform engineered around the P365 fire control unit.

Overview

The Flux Defense Raider 365 redefines the capabilities of the SIG Sauer P365 by providing a stable, three-point contact shooting platform. By replacing the standard grip module with the Raider chassis, shooters gain a shoulder brace, a forward grip, and a Picatinny rail for lights or lasers. The system collapses to a footprint smaller than a standard pistol for storage or transport, then deploys instantly for use. This design allows for accurate shots at extended ranges while maintaining the concealability of the original firearm.

Features & Specs

The Raider 365 is constructed from impact-resistant polymer and machined aluminum components. It accepts all standard P365 magazines and uses the existing slide and barrel assembly. The integrated brace is adjustable for length of pull, and the chassis includes a built-in magazine well for faster reloads. The full-length top Picatinny rail allows for mounting optics or iron sights.

• Caliber: 9mm (uses SIG Sauer P365 FCU)
• Manufacturer: Flux Defense
• Category: Pistol chassis system
• Integrated adjustable stabilizing brace
• Full-length Picatinny top rail and bottom accessory rail
• Built-in magazine well for rapid reloading
• Collapsible design for compact storage

The system retains the P365’s factory trigger and safety mechanisms. No permanent modifications are required to the firearm. Installation is straightforward: remove the FCU from the standard grip module and insert it into the Raider chassis.

Who It’s For

The Flux Defense Raider 365 is intended for experienced shooters who require a versatile platform for defensive use, range training, or competition. It is suitable for individuals who carry a P365 but want improved accuracy and control without adding significant bulk. This system is also appropriate for those with hand strength or dexterity challenges who benefit from the additional points of contact. The Raider 365 is not a toy; it is a serious tool for shooters who understand the responsibilities of owning and operating a firearm.

• Defensive carry users seeking enhanced stability
• Competition shooters in PCC or open divisions
• Shooters who prefer a brace-stabilized platform
• Owners of the SIG Sauer P365 looking to expand capability
