The Tyrant Weapon System 365 (TWS365) converts your Sig P365 into a purpose-built compact platform that goes beyond typical pistol use. Built from 7075 aluminum with proprietary polymer components, this modular chassis delivers the stability and control of a dedicated PDW while maintaining the concealability that makes the P365 platform so appealing. Weighing just 10.7 ounces unloaded, it manages to pack serious capability into a lightweight package.
The spring-loaded folding brace deploys with authority via a rear-mounted button and folds completely flush for compact storage. Unlike some competing designs, this brace actually deploys consistently and responsively every time. The removable aluminum blast shield controls muzzle blast while providing additional accessory mounting space on its bottom Picatinny rail. Everything is modular, so you can configure the system based on your needs without permanent modifications.
One of the standout features is the integrated dual-magazine system. The chassis carries your active magazine in the pistol plus a spare magazine mounted forward on the chassis, giving you a complete reload stored onboard without external pouches. This ambidextrous magazine holder accepts Sig P365 XMacro-style magazines and supports rapid reloads using familiar AR-style controls.
The TWS365 works with all P365 slide variants including standard, XL, XMacro, and compensated models. Barrel lengths from 3.1 to 6 inches are supported, so whether you're running a compact factory setup or a longer compensated barrel, this chassis adapts to your configuration. The precision-machined aluminum receiver provides a tight fit with your P365 fire control unit, and the open-top design accommodates most compensators while maintaining suppressor clearance. FCUs with external safeties can be used with minor modifications. Made in Chicago with CNC precision and backed by Tyrant's lifetime warranty.
Yes, the TWS365 works with P365 models that have manual safeties, though they may require minor modifications. Some users have successfully had the safety removed or modified the chassis, but this may require gunsmith work depending on your preference. Most users running without a manual safety find the platform works perfectly out of the box.
The chassis only works with Sig P365 XMacro-style magazines. This is important to note if you're upgrading from a standard P365, as you'll need XMacro mags to use the onboard magazine storage. The wider capacity of XMacro magazines means you get more rounds available without external pouches.
Installation is straightforward and entirely DIY. You remove your P365 fire control unit from the original grip module and install it into the TWS365 chassis, then attach the folding brace. Most people can have it assembled in under 30 minutes. The process is much simpler than building an AR or other modular platform.
Yes, it's fully compatible with compensators and most suppressors. The open-top design accommodates compensators without any interference. For suppressors, clearance depends on the suppressor's diameter. If a suppressor is too large to fit under the blast shield, you can simply remove the shield while keeping the weapon light mounted on the full-length bottom rail.
