Night Fision Optics Ready Stealth Series Sights Features The Night Fision Optics Ready Stealth Series Sights are built as a matched front and rear set for the Sig Sauer P320 designed to work alongside a slide-mounted optic rather than compete with it. Both sights are CNC machined from high quality steel for a precise fit in the P-Series dovetail and the black nitride coating adds meaningful wear and corrosion resistance over bare steel. The rear sight uses a square notch profile that pairs cleanly with the front blade for a fast repeatable sight picture. Blade heights of .315 and .302 inches are specified to co-witness correctly with slide-mounted optics. Night Fision built its reputation on moving away from the aluminum sleeves and painted white rings common to other tritium sights instead using a patented injection molded sleeve to hold tritium vials securely in place. That sleeve design creates what the company calls The Perfect Dot a brighter and more durable ring that stays visible in both daylight and low light conditions. The matte black finish keeps the sights low profile and non-reflective against the slide. The Night Fision Stealth Series Sights are available for sale at GrabAGun for P320 shooters running an optic who still want a reliable durable set of iron sights.
