The TRUGLO Brite-Site Tritium Night Sight Set for Glock 17-39 Gen 1-5 brings self-illuminating capability to your carry gun or duty pistol without batteries, light sources, or fumbling in darkness. This steel sight set uses Swiss tritium to glow on demand in low-light conditions and complete darkness, making it a reliable choice for defensive shooters, law enforcement, and anyone who trains in varied lighting. The green tritium vials are highly visible and retain brightness throughout their service life.

The design balances speed with durability. The U-notch rear sight is engineered for quick sight picture acquisition, while the angled rear sight edge allows one-hand emergency manipulation—useful if your support hand is occupied or injured. The front sight features a FOCUS-LOCK ring to help your eye settle faster on the sight picture under stress. The snag-resistant profile works with standard holsters, so you won't have to swap gear to run this set.

Built in the USA with Swiss tritium and finished in TRUGLO's FORTRESS FINISH protective coating, these sights are made to withstand hard use. The Brite-Site line has earned a solid reputation for reliability and brightness, and this set maintains that standard across the most popular Glock platforms—Gen 1 through Gen 5 models 17 through 39.
