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.

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?
