Glock 43 & 43X sights & optics

Here you find the Glock 43 & 43X accessories and upgrades we have for sighting: optic plates and red dot mounts that put a red dot on your Glock 43 & 43X, red dots that fit the optic cut directly and iron sights. Everything on this page is made for the Glock 43 & 43X, so you only need to pick the right group for your slide.

Putting a red dot on your Glock 43 & 43X

How you mount a red dot depends on your slide. Each version of the Glock 43 & 43X takes a different part:

• Glock 43X MOS: an optic plate goes into the factory optic cut and takes the red dot. We have plates for the Holosun K-series footprint. See Optics ready plates for Glock 43X MOS & 48 MOS.
• Glock 43 without an optic cut: a red dot mount goes into the rear sight dovetail in place of the rear sight. No milling, no permanent changes, and you can put the rear sight back at any time. We have mounts for the Shield RMSc footprint. See Red dot mounts for Glock 43.

Red dots with the Shield RMSc footprint fit the optic cut of the Glock 43X MOS directly, without a plate. See Direct-fit red dots for Glock 43X MOS.

Which Glock 43 & 43X do I have?

If your slide has a factory optic cut closed by a cover plate, it is Optics Ready. A slide without a cut is the classic version and takes a mount. The Glock 43X MOS has the cut. For the Glock 43 without a cut we have a mount.

Choosing a plate or mount by footprint

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 that names it. They come in steel or aluminium: aluminium is lighter, steel is heavier and robust.

Sights for the Glock 43 & 43X

Our iron sights for the Glock 43 & 43X come from Angry Bear and Night Fision. All of them fit the classic and MOS slide. If you use a red dot, choose tall co-witness sights so you see them through the window. Standard-height sights do not co-witness with a red dot. For help choosing between the sight pictures, see Sights for Glock 43 & 43X.

Frequently asked questions

Which red dot fits a Glock 43 & 43X?

Any red dot whose footprint matches a plate or mount for your slide. For the Glock 43X MOS we have plates for the Holosun K-series footprint and for the Glock 43 we have mounts for one footprint. Red dots with the Shield RMSc footprint fit the MOS cut without a plate.

Do I need a plate for a red dot on my Glock 43 & 43X?

On a MOS slide, yes, unless you choose a direct-fit red dot. A classic slide takes a mount instead.

Can I install it at home?

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

Do the iron sights work with a red dot?

Only tall co-witness sights. Standard-height sights are hidden by the red dot.
