The TruGlo TG231N1W Tritium Pro Black Front Sight with Green Tritium White Outline and Green Tritium Rear Sight delivers unmatched low-light performance for 1911-style handguns and Ruger SR1911 models, combining precision engineering with rugged durability. Built on the acclaimed PRO platform, it starts from the brightness and durability of TRITIUM night sights and adds features like a Focus-Lock front sight for faster, instinctive focus, a quick and accurate U-notch rear design, and an angled rear edge for emergency one-hand operation. Designed for Novak LoMount cut slides (.260 front / .450 rear) and crafted for compatibility with existing fixed Novak LoMount dovetails, installation by a competent gunsmith is recommended, and the Fortress Finish provides a permanent protective coating to resist wear. This sight set is assembled in the USA with top-tier Swiss tritium for maximum brightness, ensuring standout visibility in complete darkness or low-light shooting conditions without batteries or external light exposure. Its snag-resistant profile fits standard holsters, enhancing reliability when seconds count. TruGlos Tritium Pro line is the practical upgrade for serious shooters seeking immediate, precise aiming in any lighting scenario, backed by trusted American manufacturing and enduring brightness.
