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.

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.

Our modular attachments will let you carry an extra pistol mag, a 5.56 rifle mag, a subgun 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.

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.

  • Made from 0.093 precision-formed Kydex.
  • 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.
  • The holster and Spine (as well as the attachments 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.
  • Made in the USA by T.REX ARMS.

T.REX IWB Tuckable Clips are injection molded from high-strength acetal plastic. They are 3/4″ wide and 3 5/8″ long and are a Universal fit (i.e. fits belts 1.5″ to 1.75″) with a 0.5″ of adjustment. Made in the USA.

If I buy a variety of attachments, which one will come installed?
We will install attachments in this priority order:
– Pistol mag attachment
– Tourniquet attachment
– Rifle mag attachment
– Handcuff attachment
– Raptor Wing attachment
Can I attach a right-handed Sidecar to a left-handed Sidecar for akimbo/dual wield?
Akimbo is for try-hard noobs, but… yes and no. It can be done, but we did not design it with this function in mind. If you really really want to run two holsters attached to each other, email us at [email protected] and we’ll try to help you figure out a system that would actually function. (It can be complicated.)
What happens if I choose the Threaded Barrel option?
For threaded barrels, we add roughly 1/2″ of Kydex to the bottom of the holster. If you do not have a threaded barrel, you can still run it in the holster without issues. The extra length of Kydex will not affect the fitment or retention.
What frames will work in your Glock molds?
Our Glock 17 mold also fits the Shadow Systems DR920 and the Lone Wolf Timberwolf Frame. For the Shadow Systems MR920, we suggest the Glock 19 option.
Will my P80 fit in your Glock 9/40 holsters?
No, Glock 9/40 Sidecars WILL NOT fit P80 frames.
Are you still making the Raptor holster? Where did it go?
The Raptor is gone for good. The new Sidecar + Raptor Wing attachment is meant to replace it, allowing you to carry 3-5 o’clock with improved stability. We got rid of the Raptor because something better is here. The new two-point attachment system gives you much more stability and–if you train well–more consistency.
