The Night Fision GLK001010OGXG Official Costa Ludus Night Sights deliver fast, reliable target acquisition in low light with a crisp front sight featuring Green Tritium and an Orange Outline, paired with a Black Rear Sight that houses a Green Tritium Bar for clean alignment on the Glock 17/17L/17MOS/19 platform. Designed for precision and visibility, these sights fuse a distinctive orange ring around the front sight with enduring illumination, ensuring quick sight tracking during dash, dusk, or indoor scenarios where every millisecond counts. The Costa Ludus branding communicates a trusted lineage among competition and duty shooters who demand consistent performance under stress, while the low-profile silhouette reduces snag potential and preserves handling fluency.

Built for Glock handguns, these Night Fision sights support repeatable zero maintenance in adverse environments and are ideal for tactical training, competitive shooting, and personal defense where clear, fast sight picture matters.
