I just called Glock and my two choices of night sights they offer are the Glock sights and the Trijicon sights. I am local to Glock so it is very easy for me to stop by and have these installed while I wait. So I am only going to go with the two types they offer. Also they only want $57 for the Glock sights and $72 (I think) for the Trijicons. This is installed and I have no shipping. So has any one used both of these? Any opinions about which is better or how they are different? Any help would be great.
