Night Fision Pistol Optic Plate Features The Night Fision Pistol Optic Plate is machined from 17-4 stainless steel a material chosen for its strength and resistance to the repeated recoil impulses that can loosen lesser mounting hardware over time. Built to tight tolerances the plate is designed to deliver a secure and accurate fit so a mounted optic holds zero reliably. A nitride coating is applied over the stainless steel for additional protection against wear corrosion and daily holster wear. At 0.2 thick the plate adds minimal bulk to the slide while providing a stable mounting surface for the optic. This plate is designed to fit Sig Sauer P320 pistols with a factory Pro Cut slide accepting both Trijicon RMR and Holosun 507C pattern optics. The package includes extra mounting screws along with an installation tool featuring a T10 Torx head for hardware installation and a small flat head for windage and elevation adjustments. That same tool also mates with the battery compartment screw on compatible Holosun optics consolidating maintenance into a single implement. Backed by a limited lifetime warranty this plate gives P320 owners a durable and precise way to run a red dot sight on their pistol.
