Modular. Flexible. Concealable. Comfortable. Optic compatible. This is the Sidecar Holster.

The T.REX ARMS Sidecar Holster is the industry-standard solution for effective and comfortable appendix inside-the-waistband concealed carry. Our modular attachments allow you to carry things like an extra pistol mag or tourniquet alongside your firearm. The T.REX Spine System allows you to easily swap out attachments and flexes as you move to conform better to your body. This provides increased comfort and concealability, while also retaining the stability you need for maximum consistency when you draw your pistol or grab your magazine for a reload.

If you want to run your holster without an attachment (in the appendix or 3-5 o’clock position), each holster comes with our Sidecar 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. This is the most adaptable holster system on the market, and more attachments are in development.

FAQ

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
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 fits the Lone Wolf Timberwolf Frame. We have separate models for the Shadow Systems series.
Will my P80 fit in your Glock 9/40 holsters?
No, Glock 9/40 Sidecars WILL NOT fit P80 frames.
