I'm sure this is a noobish question but what is the difference of the sight height. I assume that is just to correct for the user's preferences and/or the type of rear sight that is being used. That being said, what is the standard height and how do I decide if a different height would be better (beyond just "go try some different ones").
They use Trijicon vials. Ameriglo has a sight height calculator on their website. FWIW on my G 17/19/26 and 38 I have a .165" tall front with a .256" tall rear.
