Firearm and Magazine Compatibility

It fits both the standard Glock 48 and the Glock 48 MOS. It does not fit the Glock 43X. Verify the firearm, optic, barrel and accessory configuration before checkout. The magazine carrier is intended for the compatible magazine family associated with the listed firearm. Extended baseplates, sleeves, aftermarket magazines and oversized floor plates can affect fit; contact us before ordering if your magazine is not in its original configuration.

Non-Light-Bearing Configuration

This product is not intended for a weapon-mounted light unless a light is specifically offered in the product options. Choose a dedicated light-bearing holster when a weapon light is installed.
