Red Dot Sight Reviews

Fitment

What red dot fits a Glock 48 MOS?

The Glock 48 MOS ships with a RMSc-pattern slide cut. It uses the Glock MOS (slim) adapter-plate system, so optics with a different footprint can still mount via the right plate.

Verify before buying. Fitment data is sourced and last-verified per row, but slide cuts and plate compatibility change across model years and runs. Always confirm the exact cut and plate against the manufacturer before you purchase.

Direct fit (native slide cut)

These optics drop straight onto the factory cut. There is nothing extra to buy; where an optic ships its own plate in the box, the row says so.

Full four-post RMSc cut, front and rear. A K-footprint optic (Holosun 407K / 507K) may not seat fully on the rear posts. If yours will not sit flush, the rear posts are one cause among several (a proud roll pin, an over-long striker-block screw or uneven post tops do the same), so confirm with the maker before you buy, and before you remove any material.

Fits with an adapter plate

These optics mount once you add an adapter plate. Where several plates do the job, every one we track is listed, factory part first.

No known adapter

We have not found a real adapter that mounts these optics on this gun. We list them honestly rather than guess — if a plate exists, send us the source and we'll add it.

On this slim RMSc-cut slide, a wider-footprint optic (RMR-class or larger) is not a missing-adapter case: its base is physically wider than the slide, and no plate can widen a slide to fit it.
