Night Fision GLK-002-007-OGZG Night Sights for Glock 20/21 - Orange Outline Front / U-Notch Rear

The Night Fision GLK-002-007-OGZG is a tritium night sight set engineered specifically for full-size Glock 20 and Glock 21 pistols. It pairs a square-profile front blade lit by green tritium and accented with a high-visibility orange outline ring alongside a U-notch rear lit by a matching green tritium lamp, delivering a clean, balanced sight picture from broad daylight down to complete darkness.

The orange front outline accelerates daylight pickup of the front post, while the self-illuminating tritium vials stay visible for years with no batteries or external light source required. The wide, uncluttered U-notch rear window pairs naturally with the square front for fast, intuitive target acquisition, making this set well suited to defensive carry, home defense, and low-light range work.

Designed as a direct replacement for the factory Glock sights, this front and rear set installs without permanent modification to the slide and provides a meaningful low-light performance upgrade for any Glock 20 or 21 owner.
