The HIVIZ LiteWave H3 Tritium Express Handgun Sight is a high-visibility aiming solution designed for Glock 20 and Glock 21 pistols, offering rapid target acquisition through bright green and orange LitePipe inserts paired with a white front ring for contrast in varied lighting. Built in the United States, this black and orange sight combines Tritium illumination with precise alignment to deliver dependable accuracy in low-light and duty-style scenarios, making it an ideal choice for both personal defense and professional use. The H3 triple-dot configuration provides a fast and intuitive sight picture, helping shooters lock onto targets quickly while maintaining precision at drawing distances, and the white front ring enhances sight alignment against complex backgrounds. Whether tracking a moving target at dusk, transitioning from indoors to outdoor environments, or shooting from a seated or kneeling position, the LiteWave design reduces glow on the front sight flare while preserving nighttime visibility. Compatible with Glock 20 and 21 platforms, the HIVIZ sight integrates seamlessly with existing sight dovetails and delivers rugged reliability and repeatable performance under demanding conditions, supported by a lineage of quality engineering and practical field testing.
