Glock sights & optics

Here you find all the Glock accessories we have for sighting: optic plates for Glock MOS and gen 6 ORS slides, red dot mounts for Glock pistols without an optic cut, direct-fit Glock red dots and Glock sights.

Red dots on a Glock: which slide do you have

How you put a red dot on a Glock depends on the slide. Optics Ready Glock models have a factory optic cut in the slide, closed with a cover plate. They take an optic plate that connects the cut to the footprint of your red dot. Glock models without an optic cut take a red dot mount in place of the rear sight. A mount does not fit an Optics Ready slide, and a plate does not fit a slide without the cut.

Glock uses different optic cuts on different slides, and a plate fits only the cut it is made for:

• MOS on full-size and compact slides (gen 4 and gen 5): models such as the Glock 17, 19, 26 and 34 MOS. We have plates for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter, C-More RTS, Aimpoint Acro and Holosun 509T footprints.
• Gen 6 ORS: the gen 6 has a new optic cut called ORS (Optic Ready System), and MOS plates do not fit it. We have ORS plates for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP and Aimpoint Acro footprints.
• Slimline MOS: the Glock 43X MOS and 48 MOS have a smaller cut and take their own plate for the Holosun K-series footprint.

Some Glock red dots fit the MOS cut without any plate: the Holosun SCS MOS, Vector Optics Frenzy 1x16x21 for Glock MOS and Osight SE MOS on full-size MOS slides, and red dots with the Shield RMSc footprint on the Glock 43X MOS and 48 MOS.

For Glock models without an optic cut, the mount goes into the rear sight dovetail. You need no slide milling and no permanent modifications. Most standard models take the same mounts, the Glock 21, 22 and 43 also have their own Shield Sights mounts, and a Toni System frame mount fits some gen 4 models on the frame instead of the slide.

Glock sights

Glock sights fall into two fit groups: standard models and Slimline models (G42, G43, G43X and G48). Sights from one group do not fit the other. Within a group, the same sights fit the classic, MOS and ORS (gen 6) slide. If you use a red dot, choose tall co-witness sights, so you see them through the window of the optic. Our Glock sights are made of steel by LPA in Italy, Angry Bear and Night Fision in the USA, Zendl in the Czech Republic and Eemann Tech.

Tools and spare parts

The Glock front sight is held by a screw from the inside of the slide. We have a front sight screwdriver from Angry Bear and spare front sight screws for Angry Bear sights. For the tools you need to drift sights and mounts, see Installation tools.

Frequently asked questions

Which red dot fits my Glock?

It depends on your slide and the plate or mount you choose. Every plate and mount takes one footprint or a group of footprints. Find the footprint of your red dot in its specifications and take the plate or mount for your model that names it. Pick your model above to see the options.

Is my Glock MOS or ORS?

Glock marks the generation on the slide, for example "Gen6". Gen 4 and gen 5 slides with an optic cut use MOS; the gen 6, launched in January 2026, uses ORS. A slide without a cut takes a mount.

Do Glock 17 parts fit my Glock 19?

Many do. Most mounts, MOS plates and sights for standard Glock models fit several models, and each product title names the models it fits. To be sure, pick your model above: you see only the parts that fit it.

Can I install it at home?

Yes. A plate needs no gunsmith and no milling: remove the cover plate from the optic cut, screw the plate in and the red dot onto it. A mount or new sights need a sight pusher or a punch to drift the rear sight out. Put a drop of threadlocker on every screw.
