The AmeriGlo XD191R Tritium Rear Sight transforms low-light shooting accuracy for Springfield XD and Hellcat pistols. Green tritium inserts provide constant illumination without batteries, while the white outline enhances target acquisition in daylight conditions.
What Makes This Different
Unlike standard black rear sights that disappear in poor lighting, this tritium sight maintains visibility for 12+ years through self-luminous gas capsules. The white outline creates a crisp sight picture in bright conditions where tritium glow isn't visible. Swiss-made tritium vials deliver consistent brightness rated at 25% visibility after 12 years, significantly outperforming painted or fiber optic alternatives.Key Features
