Perfection... if you want the best these are it - Trijicon HD XR Night Sights Set for Glock

i love these, i have them on all my handguns and its my go to everytime i purchase a new one. i bought my first set (which are not the same model) about 13 years ago and they still work great, not as bright as they were originally but for a tritium based product i never expected them to last this long thats why i kept buying them. brightness is top tier, the orange is easy to see in the sunlight, ill never buy a different brand. theyre tough and do the job
