Which optic adapter plates fit the Umarex Glock 45 MOS?

Dedicated full-size Glock MOS adapter plates fit the slide. For example, C+H builds plates specifically for full-size MOS models, including the Glock 17, 19, and 45 MOS, to support optics like the Leupold DeltaPoint Pro and EOTech EFLX. These plates will not fit non-MOS slides or slimline handguns like the 43X MOS or 48 MOS. Always verify that your adapter plate matches both your red dot footprint and the full-size MOS slide cut before securing the mounting hardware.

Can you mount a rear dovetail adapter plate on a Glock 45 MOS slide?

No, dovetail adapter plates are made exclusively for non-MOS slides with standard iron sight dovetails. Plates from brands like DAXISONN and Monstrum are designed to replace the rear iron sight on non-MOS Glock 17, 19, and 45 slides to host RMSc, RMR, or Docter footprints. Because the Umarex Glock 45 MOS already features a factory-milled optic cut directly in front of the rear sight, a dovetail bracket will not seat or align properly.

What caliber and action type does the Umarex Glock 45 Gen 5 MOS use?

The Umarex Glock 45 Gen 5 MOS operates as a gas blowback (GBB) airsoft gun firing standard 6mm BBs. The blowback mechanism cycles the slide with each shot to simulate standard cycling action, making it a functional trainer alongside a primary tactical air rifle. It is not compatible with .43 caliber paint markers or lead airgun pellets, so check that your ammunition matches the 6mm BB specification.

Will trigger guard holsters fit a Glock 45 MOS with a red dot installed?

Yes, minimalist trigger guard holsters readily accept slide-mounted optics because they snap exclusively over the trigger guard area. Holster designs like the UM Tactical Boltaron guard and the REXTECH trigger guard system fit Glock 17, 19, and 45 frame dimensions while leaving the top of the slide completely exposed. This open design allows red dots to clear without dragging or binding, providing a straightforward option when running sidearms alongside realistic training and plinking gear.

Do Glock 43X MOS accessories and grip sleeves fit the Glock 45 MOS?

No, accessories designed for slimline models will not fit the wider Glock 45 MOS frame. Grip sleeves like the Hogue HandAll for the 43X and 48, base pads for 6-round Glock 43 magazines, and rail-mounted lasers like the WARRIORLAND WLS-100 are made specifically for narrow single-stack and slimline dimensions. The Glock 45 MOS shares its frame profile with full-size models like the Glock 17 and 19X, so you must select sleeves and attachments rated for standard full-size frames.

How do you confirm a Glock 45 slide has the authentic MOS cut?

Check the top of the slide between the ejection port and the rear sight for a removable metal cover plate held in place by top-facing screws. A true Glock 45 Gen 5 MOS slide features this factory-milled pocket designed to receive modular mounting plates. Standard non-MOS models have a solid, unbroken slide profile with only a conventional rear sight dovetail. Confirming this milled cut prevents buying non-compatible dovetail plates or incorrect hardware kits.
