Questions & Answers
Are these the 1/3rd co-witness version? Manufacturer Answer

These sights will offer a lower 1/3rd co-witness with most optics for the 43x/48, along with direct mounted RMR height optics on full size Glock models.

These sights are Glock Gen 5 MOS compatible? Expert Answer

The Night Fision GLK11OGXG Costa Ludus Night Sight Set is not compatible with MOS model Glocks. I'd recommend the TruGlo Tritium Pro Handgun Sight Set, which will fit Gen 5 MOS model Glocks, and can be found by using the link below:

Night Fision Costa Ludus Sights by JR, Verified Owner, August 23, 2024
These sights took me a bit to get used to but after shooting a bit they became very intuitive. I really enjoy them plus they look great on my Glock 17.

Product Info for Night Fision Costa Ludus Night Sight Set

In partnership with Costa, this Costa Ludas XG Front and Rear Sight Set utilizes our patented Perfect Dot technology, which guarantees a precise front sight pin location every time you acquire your target. Additionally, this XG Tritium Sight Set from Night Fision has s serrated front sight edge to reduce glare and serrations on the rear sight edge to maximize your one-handed manipulations. On a pure tritium level, this Night Fision GLK11OGXG Costa Ludas XG Tritium Front and Rear Sight Set is incredibly bright; however, the front sight receives a white serrated edge due to the coating process. However, the rear sight has a precision cut shape that ensures the rear sight picture is large enough to acquire your target every time. Additionally, the rear sight of this Night Fision GLK11OGXG Costa Ludas XG Tritium Sight Set is optimized for sighting in the dark; the rear sight does not have serrations and therefore cannot be carried unless in an area with a great amount of light. So, these sights are incredibly useful in low-light and twilight conditions and still provide a clear sight picture. In some rare instances, this may not be enough for some shooters, so be sure you grab a Night Fision Costa Ludas Tritium Sight Set for your pistol and start shooting with one of the best sights the shooting industry has to offer.image
