The original Glock night sights are equipped with the tritium gas which lasts 15 years without having to be charged by light.

Orange at the rear and green at the front will allow you to determine where your sights are and allow you for a rapid sight alignment when it counts most.

The Glock night sights are made of a hardened steel to allow for hard handling and making it more reliable.

This is definitely a must have accessory on your self defense firearm.
