The Night Fision GLK001010OGXG Official Costa Ludus Night Sights are purpose-built for Glock 17, 17L, and 17 MOS/19 pistols, pairing a bright green tritium front dot with a high-contrast orange outline and a rear sight that uses a horizontal green tritium bar. CNC machined steel with deep serrations across both front and rear faces helps cut glare, while the low-profile square rear notch is optimized for a clean, fast sight picture and minimal interference with slide-mounted optics.

Designed for shooters who demand clear alignment in low light, this Costa Ludus set excels for range work, training, and defensive carry where rapid visual confirmation of the front sight is critical. The proprietary Perfect Dot front and distinct rear bar make it easy to separate front from rear in dim conditions, supporting confident hits without adding bulk. Night Fision’s focus on durable construction and carefully engineered tritium geometry reflects the brand’s reputation for thoughtful design and dependable performance.
