Red dots on a Sig: plate or mount

Sig models with a factory optic cut in the slide, closed with a cover plate, take an optic plate that connects the cut to the footprint of your red dot. We have plates for Sig P320 and Sig P365, for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter, C-More RTS, Aimpoint Acro and Holosun EPS footprints.

Sig models without an optic cut take a red dot mount. We have mounts for Sig 1911, Sig M11-A1 Compact, Sig P220, Sig P225, Sig P226, Sig P226 X-Five, Sig P226 X-Six, Sig P227, Sig P229, Sig P320, Sig P365 and Sig SP2022, for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter and C-More RTS footprints.

A mount is for a gun without an optic cut, and a plate fits only a slide with the cut.

Our plates and mounts for Sig come from 2BME, EGW, Night Fision, Outer Impact, Shield Sights and Toni System.

Some red dots fit the optic cut without a plate: Holosun SCS 320.

Sig sights

We have iron sights for 14 Sig models, made by Angry Bear, LPA and Night Fision. Sight pictures: blank, fiber optic, luminescent dots, tritium, white dots and white lines. Each sight is made for a specific model, so pick your model above to see the sights that fit it.

Optic plates for Optics Ready Sig models

• Sig P320: plates for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter, C-More RTS, Aimpoint Acro and Holosun EPS footprints, made by 2BME, Night Fision, Outer Impact, Shield Sights and Toni System.

Red dot mounts for Sig models without an optic cut

Several Sig models take the same mounts:

• Sig M11-A1 Compact, Sig P220, Sig P225, Sig P226, Sig P227 and Sig P229
• Sig P226 X-Five and Sig P226 X-Six
• Sig P320 and Sig SP2022

The page of each model shows the mounts that fit it.

Some makers group footprints into mount types, and the letters differ between makers, so always read the footprints in the brackets:

• EGW: type S (RMSc, DPP, K-series).
• Outer Impact: type C (RMR, RTS, Docter) and type S (RMSc, DPP, K-series).
• Toni System: type A (RMSc, DPP, Docter) and type B (RMR & RTS).

Which Sig models share sights

These models take the same sights, so you find the same sets on their pages:

• Sig P220 and Sig P226
• Sig P226 X-Five and Sig P226 X-Six
• Sig P227 and Sig SP2022
• Sig P229 and Sig P320

Tritium sights, which glow in the dark without charging, are available for the P220, P225, P226, P227, P229, P320, P365 and SP2022.

Co-witness sights, tall enough to see through the window of a red dot, are available for the P220, P225, P226, P227, P229, P320, P365 and SP2022.

Frequently asked questions

Which red dot fits my Sig?

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

How do I know if my Sig takes a plate?

A slide with a factory optic cut, closed with a cover plate, takes a plate. A slide with a rear sight in a dovetail and no cover plate takes a mount.

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.

My Sig model is not listed. What now?

We list only the models we have parts for. Find all our parts under Red dot adapters and Sights.

Do the same parts fit the Sig M11-A1 Compact and the Sig P220?

For mounts, yes: the Sig M11-A1 Compact, Sig P220, Sig P225, Sig P226, Sig P227 and Sig P229 take the same ones. Other parts can differ, so pick your model to see what fits it.

Can I change the sights on my Sig 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.
