Overview of the Trijicon Bright & Tough Night Sights | GL01
See Your Sights When the Lights Go Down
When the sun sets or you clear a dark room, plain black iron sights disappear right when you need them most. The Trijicon Bright & Tough Night Sights (GL01) solve that with three self-illuminating tritium dots that glow on their own, with no batteries and no switches. Built for your Glock standard-frame pistol, this black steel sight set gives you a fast, confident aiming point in no-light and low-light conditions.
Built Tough for Duty and Carry
Each tritium lamp sits inside an aluminum cylinder on a silicone rubber cushion, capped with a sapphire jewel and ringed in white for daylight visibility. That construction shrugs off heavy recoil and harsh cleaning solvents. Whether you carry a Glock on patrol, keep one for home defense, or shoot at an indoor range, the GL01 delivers a three-dot sight picture you can trust around the clock.

Compatibility
The GL01 set fits Glock standard-frame models: 17, 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, 39, and 45. It does not fit slim-frame Glocks such as the 42, 43, 43X, and 48, or large-frame Glocks such as the 20, 21, 29, and 30, which use different sight sets. This is an aftermarket set. GLOCK does not manufacture, authorize, or warrant it, and professional installation is recommended.
Intended Users
- Law enforcement officers who carry a Glock on patrol rely on these sights to confirm their aim during low-light stops and building searches.
- Concealed carry permit holders and armed citizens use them for home defense, where many encounters happen after dark.
- Competitive and recreational shooters who train at indoor ranges appreciate a crisp three-dot picture that holds up to high round counts.
- Gunsmiths and armorers install the GL01 set as a durable, battery-free upgrade for standard-frame Glock pistols.
What's Included
- One front night sight with a white outline and green tritium lamp
- One rear night sight with a white outline and a green, yellow, or orange tritium lamp based on the variant you choose
Installation tools such as a sight pusher and front sight tool are not included and are sold separately. Professional installation is recommended.
