Measure from the top of the slide to the bottom of the glass on the DP Pro and add .065". That will give you the height for co-witness with Leupold's rear iron sight. If you purchase your sights from DawsonPrecision.com, they have their perfect impact policy for the sights. Double check with them on exactly how it works but from what i remember, they will get you the height you need.
