Night Fision Stealth Night Sight Set Features The Night Fision Stealth Night Sight Set uses a patented injection molded sleeve rather than the aluminum sleeves and painted-on white rings found on most tritium sights. That design which Night Fision calls The Perfect Dot creates a brighter and more durable ring around the tritium vial for improved visibility in low light. A domed lens over each vial collimates the tritium rays sharpening the sight picture compared to a flat lens cover. The orange front sight configuration gives a fast high contrast reference in daylight while the blacked out rear keeps focus on the front sight. Each sight is CNC machined from high quality steel for durability under the recoil and holster wear that comes with daily carry use. A black nitride finish adds further resistance to corrosion and surface wear helping the sight set hold its appearance and function over years of use. Night Fision builds these sights in the USA using Swiss tritium a detail that speaks to the quality control behind the glow performance. Backed by a manufacturer limited lifetime warranty and sized specifically for Sig Sauer P-Series pistols this sight set is available for sale at GrabAGun.
