Hey Guys, I have a CZ P01 and I wanted to change out just the front sight to a fiber optic sight or something brighter. My old eyes suck and I want something that's a little easier to see. The problem is I don't know what is the height of the front sight. I see from 5.5 mm up to 7 mm sights. Do any of you know what is the correct height? I have stock sights not the night sights. Thanks guys.
