Ameriglo GL205 i-Dot Night Sight Set for Glock 42/43/43X/48 - Green Tritium Orange Outline Front / Green Tritium Rear

The Ameriglo GL205 i-Dot night sight set is built for fast, intuitive low-light shooting on Glock 42, 43, 43X, and 48 pistols, including MOS-equipped slides. Designed around Ameriglo's signature dot-over-dot i-Dot configuration, the set pairs a single green tritium lamp on the front post with a single green tritium dot in the rear, giving shooters a quick vertical sight picture that is easier to find than a traditional three-dot layout in defensive, home, and everyday-carry use.

The front sight features a green tritium insert surrounded by a high-contrast orange outline ring, drawing the eye to the front post the moment the pistol comes up. The rear sight carries a single green tritium lamp and supports both-eyes-open shooting with a clean, uncluttered sight picture. Both elements are housed in a CNC-machined steel body finished in matte black, built to fit factory Glock sight cuts and to co-witness with the factory slide profile.

Engineered specifically for the subcompact and slim-frame Glock platform (42, 43, 43X, and 48), the GL205 also fits Glock MOS variants of those models, making it a popular upgrade for concealed-carry pistols. Ameriglo assembles the sights in the USA using Swiss-made tritium for consistent, long-lasting illumination.
