T.REX Sidecar Pistol Mag Attachment

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.
