Glock 48 MOS

The success of the standard Glock 48 pistol led Glock to introduce the Glock 48 MOS handgun in July of 2019. This pistol is built on the standard G48 frame but offers two new features to the 48 series:

  • Glock’s Slimline MOS System for red dot or RMR optics
  • Glock Mounting Rail Slim for mounting lasers or weapon lights to the frame

The Glock Slimline MOS system features a factory slide cut designed to fit specific micro-optic red dot or RMR optics. However, this Slimline version of the MOS system differs from the standard Glock MOS system in a couple of ways. First, the Slimline MOS system will only accommodate smaller-sized optics because the rail itself is smaller than most factory light rails. Second, pistols equipped with the Slimline MOS platform do not include optic adapter plates. Instead, those plates have to be purchased separately from Glock.

The Glock Mounting Rail Slim series is a proprietary Glock rail explicitly designed for the Glock Slimline series of pistols (currently the Glock 43X MOS and Glock 48 MOS). This rail allows certain lights or lasers to be mounted under the frame in front of the trigger guard. Note that this is a proprietary rail, so it won’t fit a light or laser built to worth with a standard Picatinny rail.

G48 MOS Holster Options

Holster options for the Glock 48 MOS will be dependent on the addition of a red dot or RMR optic. If a red dot or RMR optic is mounted, then you’ll need a holster made to accommodate the Glock 48 with an optic mounted. Most holsters made for a G48 without an optic mounted will NOT fit a G48 with an optic mounted.

Glock 48 MOS IWB Holster

The most popular holster type for the Glock 48 MOS pistol appears to be inside the waistband holsters (commonly called IWB holsters).

As mentioned before, as a buyer, you have to break down the IWB holster options for the G48 MOS down into holsters made for the G48 MOS with and without an optic mounted.

Here are some frequently asked questions that we see regarding holsters for the Glock 48 MOS pistol:

Will a G48 MOS model fit into a regular Glock 48 holster?

Unfortunately, the MOS model doesn’t fit well in a holster made for a standard Glock 48, especially if the MOS version has an optic mounted. However, even a G48 MOS pistol without an optic mounted doesn’t fit into a holster made for the Glock 48 due to the proprietary rail on the 48 MOS pistol.

I landed on this page, but I’m looking for a basic Glock 48 holster. Do you offer those?

I have a Glock 48 MOS equipped with a red dot and weapon light. Do you offer any leather holsters for that set-up?

We offer leather holsters to fit a G48 MOS with a light and red dot mounted; however, it depends on the specific make and model of the light. Any holster listed below can be built to fit that specific G48 version with most mainstream weapon lights and red dot optics mounted.

Any of the holster models displayed below are available in a configuration to fit a Glock 40 MOS, including a G48 MOS equipped with a weapon light, red dot optic, or one equipped with both accessories.
