To consider a gun to be great, it must be reliable day and night. Providing a consistent green glow, Rival’s tritium night sights ensure accuracy in low light and even complete darkness. In daylight, a large orange dot and rounded notch design increase speed and accuracy. The frame was CNC-machined of stainless steel construction, snag resistant design. Designed to fit all double stack 9mm Glock models. Standard height models directly replace factory sights and are designed to fit in standard holsters.
