Ruger Mark III sights & optics

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

Putting a red dot on your Ruger Mark III

• Optic plate: for a slide with a factory optic cut closed with a cover plate. The plate goes into the cut and takes the red dot. We have plates for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter and C-More RTS footprints. See Optics ready plates for Ruger Mark III.
• Red dot mount: carries the red dot on a Ruger Mark III without an optic cut. We have mounts for the Trijicon RMR, Shield RMSc, Holosun K-series and Leupold DPP footprints, made by EGW. See Red dot mounts for Ruger Mark III.

A plate fits only a slide with the optic cut, and a mount is for a Ruger Mark III without it.

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.

Frequently asked questions

Which red dot fits a Ruger Mark III?

Red dots with the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter and C-More RTS footprints, on the plate or mount for your pistol.

Can I install a plate 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. Put a drop of threadlocker on every screw.

Can I change the sights on my Ruger Mark III at home?

Yes, with a sight pusher or a punch. Drift the old sight out of the dovetail and push the new one in. If you do not have the tool, a gunsmith can do it for you.
