Fixed, low-profile combat sights are drop-in replacements for factory sights and feature streamlined contours with rounded corners to help prevent snags and hanging-ups. Precision-machined steel sight bodies sit low in the slide to resist catching on clothing during the draw, yet stand up to the abuse of hard operational and competition use. Night sights have two self-illuminating, Trijicon® Tritium inserts in the rear sight and one in the front blade to provide an easy-to-see, 3-dot sight picture in low-light conditions. Helps you acquire the sights and get on target quickly under stress. Works like a simple, 3-white-dot system for enhanced visibility in daylight. Nothing to turn on: as the ambient light gets lower, the Trijicon® Tritium dots start glowing. Ghost Ring rear aperture sight uses the eye’s natural ability to center objects in a circle to aid in fast target acquisition. Tritium dots on each side of the ghost ring are smaller than the front sight dot to eliminate confusion during sight alignment. Green front sight insert; available with Green or Yellow rear dots.
