The HIVIZ LiteWave Handgun Rear Sight for Glocks 9mm/40 is designed to elevate reliability and confidence with its all-steel construction and durable LiteWave technology. This interchangeable LitePipe sight system includes green, red, and white Litepipes to adapt to varying light conditions, ensuring fast target acquisition and improved visibility across common shooting scenarios. Featuring a LitePipe diameter of 0.090 and a blade width of 0.125 by 0.135 inches, it pairs with factory height front sights for seamless alignment with the factory rear sight, and is specifically compatible with Glock models in 9mm, .40 S&W, and .357 Sig while not fitting 42 and 43. The installation is supported by a recommendation for professional gunsmith installation when used on CZ sights, and the design emphasizes long-term durability with all-steel construction and a limited lifetime warranty under normal use. This handgun sight set also includes the Replacement LitePipe Handgun version #5, making it a practical upgrade for shooters seeking clarity, consistency, and rapid sight picture in a compact, US-made solution.
