Optics ready plates for Sig Sauer models

Optics ready plates for Sig Sauer models

(14 products)

Sig Sauer pistols are widely recognized for their precision and reliability, making them a top choice for both tactical and competitive shooters. Many current models come Optics Ready from the factory, allowing for easy mounting of red dot sights.

This category includes red dot mounting plates for Sig Optics Ready models. Some models let you keep your iron sights co-witnessed with your optic. That’s ideal if you prefer backup sights or want a consistent sight picture. Explore all CoWitness Sig sights here.

We offer mounting plates compatible with almost every red dot pattern available today, including options for:

Trijicon RMR footprint
Leupold Delta Point Pro footprint
Noblex / Vortex Venom footprint

Here you can find plates for these Sig models:

Have a non-Optics Ready Sig? We’ve got you covered

If your Sig model isn’t Optics Ready from the factory, you can still mount a red dot using our dedicated red dot mounting solutions. These mounts attach via the rear sight dovetail or slide milling, depending on the model.

Find all compatible red dot mounts for Sig Sauer pistols here, including options for classic models like the P226, P229, and P220.

Efficacité

Bonjour, mon expérience chez Optics Spot est très satisfaisante, produit conforme et reçu en 72h, j'ai du renvoyer l article car non compatible avec ma hausse et y a eu une très bonne communication avec Paul.
Les tarifs sont correcte les FDP aussi. Je recommande cette compagnie.

Everything ok.

Lieferung schnell wie angekündigt. Lieferstatus wurde mitgeteilt. Das Produkt passt wie bestellt. Alles ok, gerne wieder.

EXCELLENT!!!! As the Terminator says; I'll be back!

I ordered adjustable sights for my CZ 75 Shadow, but accidentally ordered the wrong one (without the white dots). I sent a mail on a Sunday, and that was answered the same day, and the order was changed instantly. The right set arrived from the Czech Republic to The Netherlands on Tuesday morning.

Thanks for the Excellent service Paul.

Sig Sauer P220, 225, 226, 227, 229, 320 red dot mount universal | type B

PERFECT FIT - EASY TO INSTALL - SUPERIOR PRODUCT -Thrilled with purchase

I bought another mount (from a vendor in Quakertown, PA, USA) which was horrible, badly machined, so badly machined I had to use a file for hours to make it fit on a HK VP9. Then, I went to Optics-Spot, for my P226 Legion needs.

John, the customer rep., was on the phone with me for fifteen minutes at 2:00 AM (Eastern U.S. Time). He found this perfect mount for my Sig Sauer P226 LEGION (in .40S&W caliber). This gun is very rare and highly-collectable, so it was essential the mount fit perfectly without marring the pistol.

It fits PERFECTLY. Instead of hours of filing, just drove it into the dovetail with a hard plastic-faced hammer and it snugged-up PERFECTLY. Set screws for the dovetail fit and tightened perfectly, also.

This "Universal Mount" comes with "drop-in" lugs (keep the reflex sight from moving horizontally) which appear to be machined to 0.0001 inches, or better, so tight that there's no measurable movement but they dropped-into the recesses amazingly well.

This is a VERY, VERY IMPRESSIVE, QUALITY PRODUCT, sold by a superb company, "Optics-Spot," with extraordinary customer service.

Cudos go out to John, and Optics-Spot!

Vector Optics Frenzy 1x22x26 MOS red dot

Awesome service and communication

The attention and advices were very useful.
I'm really happy with my red dot optics, even when I'm still having issues to adapt them to my pistols. But I'm sure I'll make it work soon.
