The HiViz LiteWave Rear Sight for the Glock 42 and 43 (brand part number GLLW11) is a green fiber optic rear sight built to sharpen the sight picture on these compact single-stack carry pistols. HiViz machines this sight with an all-steel frame for durability and pairs it with interchangeable LitePipes, so shooters can swap fiber optic elements as they wear or as lighting conditions change. The rear notch and factory-height geometry are precisely dimensioned to work with HiViz’s own front sight, giving a consistent, fast sight picture for concealed-carry use. It’s a direct-fit upgrade for Glock 42/43 owners who want a brighter rear reference without changing their factory sight radius.
