Red dot adapters for Ruger models

This collection brings together every red dot adapter we have for Ruger models: optics ready plates for Ruger models with a factory optic cut, and red dot mounts for Ruger models without one. Pick your model above and you see only the plates or mounts that fit it.

Plate or mount: which one does your Ruger model take

• Optics Ready Ruger models have a factory optic cut in the slide, closed with a cover plate. They take an optics ready plate. The plate goes into the cut and connects it to the footprint of your red dot.
• Ruger models without an optic cut take a red dot mount. The mount replaces the rear sight in its dovetail. You need no slide milling and no permanent modifications.

A mount does not fit an Optics Ready model, and a plate does not fit a model without the cut. Choose your exact model, including the Optics Ready (OR) or MOS part of its name.

The Ruger Mark III and Mark IV are an exception: they take both. A plate installs on top of the slide and the rear sight stays, or a mount replaces the rear sight. See Red dot adapters for Ruger Mark III and Red dot adapters for Ruger Mark IV.

Optics Ready Ruger models

We have optic plates for Ruger pistols with a factory optic interface. Plates are available for the Ruger 57, the Mark III and Mark IV, and the Max-9.

Which plate fits which Ruger

• Ruger 57: Outer Impact type C fits Trijicon RMR, C-More RTS and Docter. Type S fits Shield RMSc, Leupold DPP and Holosun K-series. See Optics ready plates for Ruger 57.
• Mark III and Mark IV: one plate family fits both. The same type C and type S options are available. See Red dot adapters for Ruger Mark IV.
• Max-9: a plate for the Trijicon RMR footprint by EGW. See Optics ready plates for Ruger Max-9.

The plates are machined from aluminium in the USA.

Installation

Remove the factory cover plate from the optic cut. Screw the optic plate into its place, then screw the red dot onto the plate. No milling is needed and you can do it yourself. Threadlocker on the screws is recommended.

Ruger models without an optic cut

We have red dot mounts for Ruger pistols, revolvers and the 10/22 rifle. The mounts replace the rear sight, with no slide milling or permanent modifications.

Which mount fits which Ruger

• Mark series, P85 and P97: one EGW mount family. It comes for the Trijicon RMR or as type S for Shield RMSc, Leupold DPP and Holosun K-series. See Red dot mounts for Ruger Mark IV.
• SR9, SR40 and SR45: an EGW mount for the Trijicon RMR. See Red dot mounts for Ruger SR9.
• Security 9: mounts for the Trijicon RMR and Outer Impact type C. See Red dot mounts for Ruger Security 9.
• American: Outer Impact type C. See Red dot mounts for Ruger American.
• 10/22: Outer Impact type C, which replaces the rear sight of the rifle. See Red dot mounts for Ruger 10/22.
• Revolvers: an EGW type S mount for the Blackhawk, Redhawk, GP100 and other Ruger revolvers. See Red dot mounts for Ruger revolvers.

Outer Impact type C fits Trijicon RMR, C-More RTS and Docter. EGW type S fits Shield RMSc, Leupold DPP and Holosun K-series.

Installation

Drift the rear sight out of the dovetail with a sight pusher or a punch. Push the mount into the same dovetail and fix it. Then screw the red dot onto the mount. No slide milling or permanent modifications are needed. See Installation tools.

Frequently asked questions

Can I install the plate on my Ruger at home?

Yes. No milling is needed, and you can do it yourself. Screw the plate onto the factory interface of your pistol, then screw the red dot onto the plate. Put a drop of threadlocker on every screw.

Which red dots will fit my Ruger?

It depends on the plate you choose. Every plate takes one footprint or a group of footprints. For Ruger pistols we have plates for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter and C-More RTS footprints.

Choose your red dot first and find its footprint in the specifications. Then take the plate with the same footprint.

Does a Mark IV plate fit my Mark III?

Yes. The plates are made for both the Mark III and the Mark IV.

Can I put a red dot on my Ruger without an optic cut?

Yes. The mount goes into the rear sight dovetail in place of the rear sight. No milling and no permanent changes, so you can put the rear sight back at any time.

Does the Mark mount fit my P85?

Yes. The EGW mount is made for the Mark series, the P85 and the P97.
