GL101O (Orange Front Sight). Works with the G17/L, 19, 22, 23, 24, 26, 27, 33, 34, 35, 38, 39.

The HD Night Sights were specifically created to address the needs of tactical shooters.
The three dot green tritium night sight set's front sight features a taller blade and an aiming point ringed in photoluminescent paint while the rear sight is outlined in black and features a wider U-shaped notch. This unique configuration increases visibility and quickens front sight acquisition --even in transitional lighting.

Additionally, the front surface of the rear sight is steeply hooked to assist in emergency one-handed slide operation. The Hard Duty Night Sights are designed to shine --even in the most demanding conditions.

Green tritium lamps are warranted for 12 years from date of manufacture
