The TruGlo Tritium Pro Handgun Sights for Glock High Set deliver a proven upgrade to night sight performance, combining premium Swiss tritium brightness with PRO level features for unmatched 24/7 visibility and reliability. Built to maintain the factory sight radius, this compact design integrates an orange FOCUS-LOCK ring on the front sight to deliver faster, sharper focus in every lighting condition, while the angled rear sight edge enables one-handed manipulation in emergency scenarios. Assembled in the USA with high-quality tritium, these sights glow without batteries or external light exposure, ensuring you can acquire your target quickly in low light, dawn, or night sessions. The Fortress Finish nitride coating adds durable protection against the rigors of daily carry and hard-use environments, keeping the sights looking and performing at their best, shot after shot. Specifically designed for Glock handguns, these sights fit standard holsters and provide improved contrast and sight picture for precision aiming, fast target acquisition, and responsive follow-up shots in any environment.
