Front Sight Height

Glock with RMR & Rear Sight Delete

I recommend front sight that is 0.315" tall. If you put the front sight in the middle of the window, with the dot right on top of the bottom edge of the window, it's point of aim will be almost exactly the same as the red dot, should the dot malfunction and you need to use the front iron.
