The three dot 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 MOS Fit sights are NOT intended to be used while also running a red dot as they are not tall enough to be viewed through the red dot window.
