Somewhere on GT, I have seen a picture of a Glock rear sight that appears to be a shallow "V" with a luminous center line. I have looked all over and can not find it again. Can someone help me find it? I am hoping to be able to adapt it as a rear sight for my Ithaca 37 Deerslayer along with a fiber optic front sight. The factory sights are just too blurry for my old eyes. I have fired British double rifles with express sights in this configuration and can see them much better. The only problem is that the sights on these rifles cost more than my Ithaca and Glocks put together. Thanks for any help.
