I had Trijicon night sights on a Glock26 and thought that they were worth the cost. In a very low light area like my driveway at night, the black Glock would totally disappear in front of me. The night sights solved that problem. You may feel differently, but I felt that $80 wasn't too much to put into sights with a life span of 10-13 years. Averages $8 a year for a good night sight system. Not too bad in my opinion.
