Night Fision GLK002007YGW Perfect Dot Tritium Night Sights for Glock 20/21/29/30/36/40/41 - Square Front / U-Notch Rear

Upgrade your Glock with the Night Fision GLK002007YGW Perfect Dot Tritium Night Sights, a precision-engineered front/rear sight set purpose-built for the Glock 20, 21, 29, 30, 36, 40, and 41. Designed as a direct replacement for factory sights, these install cleanly on full-size and compact Glock duty pistols used for carry, home defense, and range work.

The sights are built on a rugged steel frame finished in black to handle years of recoil and abuse. The front sight carries green tritium with a yellow outline for fast, high-contrast daylight acquisition, paired with a rear sight that uses green tritium with a white outline. The classic Square Front / U-Notch Rear configuration produces Night Fision's signature Perfect Dot sight picture - the bright tritium front ring settles cleanly between the two rear tritium vials for an unmistakable aiming reference in low light or total darkness.

Night Fision packs more tritium than the average night sight and pairs each vial with a domed lens engineered to produce a crisp, defined glow. Tritium is self-powered with no batteries required, and these sights are backed by Night Fision's 17-year warranty. They drop directly into the factory Glock dovetails with no windage or elevation adjustment needed.
