I somehow have aquired way too many night sights. In the process, I have owned them all, including about 6 pair of Trijicons and two pair of Meprolights.
The Trijicons are okay, they do the job.
The OLD Meprolights I have are not any better than Trijicons, they are very similar.
But, the NEW Meprolights I have (less than a year old) are GREAT!!! These are some of my favorite sights. I have them on my Glock 19. The white dots are real big and bright during the day time, and the inserts are very bright at night. The white parts are covered with a glass-type covering that makes them look great.
Trijicons on the other hand SUCK in that department. Trijicons have no covering over the white inserts, and the white stuff flakes out! not only that but the white part is very thin and they are not real easy to see in the day time against a black target.
Meprolights on the other hand get an A+ in these departments.
Go with Meprolights! From someone that has owned them all, the new Meprolights are Great!!!
Ps- Is that the Police Supply place in San Diego on El Cajon Blvd? If so, I suggest that you DO NOT go there. They sold me a defective flashlight, and when I went back the very next business day, they said they would not take it back because it was used. I called them when I got home right after I bought it, and they were closing, so then went back the next businees day, and they were total jerks, all of them including the owner. Very very rude. All I wanted was my money back because they sold me a defective product the day before, and they refused to help me in any way and were very rude about it. I will never go in there again and I suggest you spend your money in a place that has some class. So to "So. Cal Guns" or "American Shooting Center" or ANY other place. Or, ship your slide to Glockmeister and they will install them for like $65 or so. (www.glockmeister.com)
