The Glock Pyramid Sights system by OuterImpact is our initial design for lightning fast acquisition. The Pyramid Sight system offers four configurations (Starter, Standard, Firefly, and Master) for maximum flexibility. All of the OuterImpact Glock  pyramid sights systems feature steel front and steel rear sight bases. The Standard and Master Kits include five different front and rear polymer color options to best match your eye’s instinctive preference. The Starter and Standard kits are able to be upgraded with OuterImpact’s polymer Firefly front inserts, or the Firefly kit can be used as a stand alone system. The Firefly kit includes both Coral and Yellow, will never lose the ability to charge and continue glowing for hours. Firefly provides you the advantage in low light/no light scenarios.

This unique pyramid sighting system covers up only the smallest possible portion of your target. The sight is simple to align, naturally intuitive, and smooth; providing pin point accuracy. The OuterImpact Pyramid Sight system is completely customizable to create your preferred contrast. Windage and elevation adjustment make these the most accurate sights you will ever use.
