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 (Yellow) 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.

Professional installation recommended.
