NF OPTIC PLATE RMR/507C SIG P320 BLK

Description

The Night Fision Pistol Optic Plate for the Sig Sauer P320 Pro Cut bridges the gap between the factory optics-ready slide and red dot sights that use the RMR footprint — including the Trijicon RMR and Holosun 507C — without requiring any machining or custom fitting. The P320 Pro Cut slide presents its own proprietary mounting interface, so a direct-mount optic in the RMR footprint simply will not seat correctly without an adapter like this one. This plate solves that mismatch cleanly.

Night Fision machines the plate from 17-4 stainless steel, a grade chosen for its combination of tensile strength and resistance to the repetitive shock of pistol recoil. A nitride coating over the stainless adds a layer of corrosion and surface hardness protection without appreciably changing the plate’s dimensions. At 0.2 inches thick, the plate does raise the optic slightly relative to flush-mounted configurations, which is worth accounting for when selecting suppressor-height or standard-height iron sights to co-witness through the optic. Night Fision publishes a Pairing Guide specifically to help shooters work through that co-witness geometry.

Installation hardware is included — extra screws and a dedicated optic tool with a T10 Torx head for the mounting hardware and a small flat head for optic adjustments and battery compartment access. The tool includes a lanyard hole, keeping it accessible at the range without hunting through a bag. A limited lifetime warranty covers the plate, and Night Fision offers a full refund within 30 days if the fit or function does not meet expectations.
