HK111O. H&K 45 HD Night Sights (orange).

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 HD Night Sights are designed to shine --even in the most demanding conditions.
