The Night Fision Costa Ludus is a tritium night sight set for the Glock 17, 17L, 17 MOS, and 19, designed with direction from Chris Costa based on his background as a firearms instructor, sold by Night Fision (brand part no. GLK001010OGXG). The front sight uses Night Fision’s proprietary Perfect Dot tritium insert while the rear sight uses a horizontal tritium bar, giving a clear front-to-rear distinction in low light, and serrations on both sights cut glare while aiding one-handed manipulation. CNC machined from high-quality steel with a black nitride coating, the set is cut to an extreme low-profile co-witness height recommended for use with a Holosun c-series or Trijicon RMR Type 2 red dot. It’s built in the USA using Swiss tritium.
