Optics ready plates for Sig P320-M17

The Sig Sauer P320-M17 is the military-style member of the P320 family, using a factory optics cut designed around the Leupold DeltaPoint Pro / Romeo1Pro footprint. When you remove the original cover plate, you also remove the rear sight, so choosing the right adapter plate is key if you want to keep or restore a usable sight picture.

This category gathers optics ready plates made specifically for Sig P320-M17 pistols. Whether you want a low-profile competition setup or a plate with an integrated rear sight for duty and defensive use, you’ll find plates here that match both the M17 optics cut and your chosen red dot footprint.

Understand your M17 optics cut & rear sight

All factory P320-M17 slides share the same basic optics layout:

• DPP / Romeo1Pro-style cut: The slide is machined for the DeltaPoint Pro / Romeo1Pro footprint. The factory cover plate fills this cut and also carries the rear sight.
• Rear sight integrated in the cover plate: When you remove the cover plate to install an optic, the rear sight comes off with it. To retain a traditional sight picture or co-witness capability, you’ll typically want an adapter plate with an integrated rear sight or a solution that adds a new rear notch on top of the slide.

The plates in this category are built around that exact configuration, so you don’t have to guess whether a given adapter really fits the M17 slide.

Plates available for major red dot footprints

Our P320-M17 adapter plates support a wide range of popular red dot mounting patterns, including (model-dependent):

• Trijicon RMR / SRO and compatible optics
• Leupold DeltaPoint Pro / Romeo1Pro-type optics
• Shield RMSc
• Holosun K-Series
• Noblex / Vortex Venom-type footprints
• Aimpoint ACRO
• C-More RTS and similar competition optics

Always check the individual product description for the exact combination of P320-M17 slide + optic footprint that each plate supports.

Precision fit for the Sig P320-M17

Each plate in this collection is CNC-machined specifically for the M17 / P320-M17 optics-ready slide. You’ll find:

• Low-profile plates that keep the optic as close to the bore as possible for faster target acquisition.
• Plates with integrated rear sights or rear-sight solutions for shooters who lose their irons when removing the factory cover.
• Competition- and duty-focused designs that balance durability, window exposure, and snag-free contours for holster use.

This lets you tune your M17 for service, carry, or sport while maintaining a secure mount and repeatable zero.

Iron sights & backup sighting options

If you want a traditional sight picture or a backup to your red dot, we also offer iron sights for Sig P320 optics-ready models, including suppressor-height sets for co-witness, fiber optic fronts, and tritium night sights. For the M17, look for solutions that either integrate a rear sight into the plate or mount a rear notch directly behind the optic.
