At the moment, black is the only color for Sidecar attachments.
Modular. Flexible. Concealable. Comfortable. Optic compatible. This is the new Sidecar Holster.
For the last six years, the T.REX Sidecar has been the industry-standard AIWB (Appendix Inside the Waistband) holster. But now we’ve updated this holster with the T.REX ARMS Spine System—a modular hinge system that allows the holster and preferred attachment to flex as you move and conform better to your body. This provides maximum comfort and concealability, but since it is a single-axis pivot system, it also retains the stability you need for maximum consistency when you draw your pistol or grab your magazine for a reload. Watch the video below for an in-depth look at the new Sidecar holster, all its features, and how to adjust it to fit your needs.
The holster and Spine (or attachment and Spine) are formed from a single piece of Kydex, making it the smoothest and simplest design of any flexible holster system. The holster is connected to the attachment by a machined steel pin, which lends the Spine strength and creates the ability to quickly and easily swap out attachments.
The Sidecar is compatible with standardized slide-mounted optics mounted behind the ejection port (not compatible with optics mounted on the frame or over-hanging the ejection port) and with suppressor height sights up to 0.5″ tall.
Our modular attachments will let you carry an extra pistol mag, a 5.56 rifle mag, a tourniquet, or handcuffs, all with adjustable retention and all securely attached to the holster at user-adjustable ride heights. This is the most adaptable holster system on the market, and more attachments are in development.
If you want to run your holster without an attachment (in the appendix or 3-5 o’clock position), each holster comes with our new Raptor Wing, which has a stabilizing belt clip and mounting holes that can be used to attach knife sheaths or other tool holders so you can easily assemble your own attachments.
On that note, the design of our new T.REX ARMS Spine System is totally open source. Any holster manufacturer who would like to build Spine-compatible attachments can download blueprints and CAD models here and help build out the capabilities of the wider Sidecar ecosystem.
Other upgrades we made from the previous Sidecar generation include better retention, more adjustability of holster ride height and cant, and better compatibility with optics and suppressor-height sights. We’ve also completely overhauled our manufacturing pipeline to improve overall quality and consistency.
