Overview

This pistol mag carrier allows you to carry a spare magazine in the appendix position—just like the original Sidecar Appendix Rig—but with the added benefit of flex down the middle and adjustable mag ride height. It attaches to the Sidecar holster via the Spine System with a pin and friction washer.

This mag carrier offers more adjustable retention points than the original Sidecar as well, five to be exact, and they can be tweaked to give you the perfect fit on your magazine. Watch the product overview video for installation and adjustment instructions.

What's Included

  • 1x T.REX Sidecar Pistol Mag Attachment
    • T.REX IWB Tuckable Clip (installed)

Specs

Made from 0.093 precision-formed Kydex. Has five retention adjustment screws. View the Sidecar Hardware Diagram HERE.

The attachment and Spine are formed from a single piece of Kydex for a smooth and flexible design. The attachment is connected to the holster by a machined steel pin, which lends the Spine strength and creates the ability to quickly and easily swap out attachments. Can be mounted to the Sidecar at your desired height.

Note
This is NOT a standalone product. It is designed to be attached to the new Sidecar holster.

Made in the USA by T.REX ARMS.

IWB Tuckable Clips: Available in high-strength acetal plastic or heat-treated C1050 spring steel with a durable powder-coat finish. Fits belts up to 1.75″.

FAQ

Could I attach this to a Sidecar without the friction washer?
The question isn't really could you, but should you. While the Spine pin is very secure even without the friction washer, it’s wise to build in redundancy. If you need replacement hardware, you can find it here.
