Red dot mounts for Sig Sauer P320

(5 products)

Upgrade your standard Sig P320 with a red dot sight—no custom slide work required. These mounting solutions fit into the rear sight dovetail, letting you equip an optic without any permanent modifications.

Note: These mounts are designed for non-optics-ready P320 models. If your Sig P320 features a factory optics-ready slide, head over to our dedicated adapter plate collection - as we explain further in the text.

Red dot mounting options for Sig P320 (non-OR)

Whether you're setting up for concealed carry, competition, or everyday range use, these dovetail mounts offer a secure and reversible way to run a red dot—no milling or gunsmithing required. Compatible with factory slide cuts on standard (non-OR) P320 models.

Supports major red dot optics

Choose a mount that matches your optic. Our selection covers many popular footprints, including:

Trijicon RMR / SRO
Holosun 407C / 507C / 508T
Shield RMSc
Leupold DeltaPoint Pro
Vortex Venom / Docter footprint
Aimpoint Acro
C-More RTS

Why add a red dot to your Sig P320?

Outfitting your P320 with a red dot sight can provide real performance benefits:

Quicker target acquisition and faster follow-ups
Improved shooting accuracy under pressure
Completely reversible—no drilling or slide cuts
Compatible with trusted optic brands

Take your standard Sig P320 to the next level with a modern sighting system—without permanent modifications or costly slide work.

Need iron sights for your Sig P320?

We also offer high-performance iron sights for various P320 models. Whether you're replacing factory sights or upgrading, we have you covered.

Using a Sig P320 Optics Ready slide?

If your P320 comes with a factory OR slide, you’ll need a red dot plate, not a dovetail adapter. Browse our selection of optics-ready plates below:

Besz for Shadow01

I did not have to machine the slide. It just pops on, you do not need gun master to install.
The plate covers the space between the itself and the slide. You can install it to the middle of the slide only. It does not move at all.
