Red dot mounts for Sig Sauer models

(8 products)

Sig Sauer pistols are celebrated for their innovation, accuracy, and rugged performance—favored by professionals and enthusiasts across the globe.

As more shooters embrace red dot optics for quicker sight alignment and improved shooting speed, outfitting your Sig with the right mounting solution becomes essential.

We offer a wide range of red dot mounts for popular Sig models like the P320, P365, P226, and more. No permanent modifications or slide milling required.

Compatible with major red dot footprints

Our mounts support a variety of popular red dot standards through dovetail adapters or optics-ready plates, including:

  • Trijicon RMR footprint
  • Leupold Delta Point Pro footprint
  • Shield RMSc footprint
  • Holosun K-Series footprint
  • Noblex / Vortex Venom footprint
  • Aimpoint Acro footprint
  • C-More RTS footprint

Red dot mounts for leading Sig Sauer models

Even if your Sig isn't factory-milled for optics, you can still mount a red dot using one of our dovetail-based adapters that replace the rear sight. You'll find them all in this category.

All mounts are engineered for secure fitment and easy installation—no gunsmithing needed.

How to pick the right red dot mount for your Sig

Start by identifying your Sig model. Then choose a mount that matches your red dot's footprint. Use our product filters or browse by model below:

Not sure which mount fits your Sig?

If you need help selecting the right mount or footprint, contact us. We're happy to help you get the perfect setup for your Sig pistol.

Got a factory Optics Ready Sig?

If your Sig pistol has a factory optic cut, you might be looking for an optics-ready mounting plate rather than a dovetail adapter. Find them here: Optics Ready plates for Sig Sauer pistols.

Looking for sights for your Sig?

We also offer premium iron sights for Sig models—ranging from fiber optics for competition to rugged carry-ready options. Browse our full Sig sights collection.
