Night Fision Sight Set Features The Night Fision Sight Set is built with a steel frame designed to hold up under hard use while maintaining a consistent reliable sight picture on a Glock 20/21. Steel construction resists the wear and impact that polymer sights can suffer over years of holster draws and daily carry. The orange front sight color is chosen specifically for its visibility helping the shooter acquire the front sight quickly in bright daylight or against a cluttered background. Fast front sight acquisition translates directly into quicker more confident shots in a defensive encounter. Night Fision has built its reputation on producing sights that perform in demanding law enforcement and personal defense roles and this set continues that standard for Glock 20/21 owners. A dedicated fitment for the 20/21 platform means the sight set installs as a direct factory replacement without modification. Shooters upgrading their factory sights gain a more visible more durable sighting option suited to range training concealed carry and duty use alike. This Night Fision set gives Glock 20/21 owners a straightforward upgrade path to a more capable sight system.
