The Springfield 1911 Dark Diamond Sight system by OuterImpact uses the same fast target acquisition technology from the proven Pyramid sights system, but adds the dark diamond shape, making it better suited to low light scenarios.

The polymer front sight of the Dark Diamond is visible day or night and gives the shooter an excellent point of reference at probable engagement distances, allowing for the quickest shots on target. Aligning the diamond with the rear sight gives pin point accuracy at distant objectives, while striving to cover up the smallest portion of the target possible.

The Dark Diamond by OuterImpact features steel front and steel rear sight bases along with our tested polymer Firefly front sight insert in Coral, Yellow and Aqua. Giving the user the choice best suited to their natural eye preference.
