Optics ready plates for Sig P320-XCOMPACT

The Sig Sauer P320-XCOMPACT is a compact X-Series pistol designed for carry and dynamic shooting. Many factory models are optics ready, using a slide cut that makes it easy to add a red dot without permanent modifications.

In this category you’ll find optics ready plates made specifically for Sig P320-XCOMPACT models. All XCOMPACT optics-ready slides share the same base cut (Leupold DeltaPoint Pro / Romeo1Pro type). Some versions also include additional RMR-pattern screw holes, but the plates themselves still locate on the original DPP cut and recoil lugs.

In practice this means you choose your adapter plate by model (P320-XCOMPACT) and by optic footprint – not by minor differences in screw-hole layout. For RMR-type optics we strongly recommend using a dedicated adapter plate instead of mounting the optic directly to the slide, so that recoil is transferred safely through the plate and its pins.

Plates for the most popular red dot footprints

Our P320-XCOMPACT plates cover a wide range of mounting patterns (model-dependent), including:

• Trijicon RMR / SRO
• Leupold DeltaPoint Pro / Romeo1Pro-type cuts
• Shield RMSc
• Holosun K-Series
• Noblex / Vortex Venom
• Aimpoint Acro
• C-More RTS

Always check the individual product description for the exact combination of P320-XCOMPACT slide + optic footprint that each plate supports.

Optimised for compact carry and performance

Each adapter plate in this collection is CNC-machined specifically around the Sig P320-XCOMPACT optics-ready cut. You’ll find options such as:

• Low-profile plates that keep the red dot as close to the bore axis as possible.
• Plates tuned for fast target acquisition and a wide optic window for sport or dynamic shooting.
• Versions that allow co-witness or backup sighting solutions (depending on model and sight set).

This lets you configure your XCOMPACT for concealed carry, range work, or competition while maintaining a secure mount and reliable zero retention.

Non-OR P320 or other Sig models?

If your Sig P320 is not optics ready from the factory, you’ll need a dovetail or dedicated mount instead of a plate for the slide cut. These options are gathered here: red dot mounts for non-OR Sig P320 pistols.
