Glock 27 sights & optics

Here you find the Glock 27 accessories and upgrades we have for sighting: red dot mounts that put a red dot on your Glock 27 and iron sights. Everything on this page is made for the Glock 27, so you only need to pick the right group for your slide.

Putting a red dot on your Glock 27

• Glock 27 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 Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter and C-More RTS footprints. See Red dot mounts for Glock 27.

Choosing a mount by footprint

Every mount takes one footprint or a group of footprints. Find the footprint of your red dot in its specifications and take the mount that names it. The type letters (type A, type S…) differ between makers, so always read the footprints in the brackets. They come in steel or aluminium: aluminium is lighter, steel is heavier and robust.

Sights for the Glock 27

Our iron sights for the Glock 27 come from Angry Bear, Eemann Tech, LPA, Night Fision and Zendl. All of them fit the Glock 27. 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 27.

Frequently asked questions

Which red dot fits a Glock 27?

Any red dot whose footprint matches a plate or mount for your slide. For the classic slide we have mounts for six footprints.

Can I install it at home?

Yes. 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.
