The dots on the rear sight were bad enough that they weren't a distraction, so I didn't change them out. As long as you order the right height front sight it shoul be the same POA. The bushing may adjust your POI if you get one....
BTW Jackinil that is good looking!
All factory front sights on the CZ 75's will be the same height, 5.5 mm. Rear sights are where they make their adjustments. Usually they will be a #3, 4 or 5.
Not sure about the higher end or competition gun sights, seems like I heard somewhere that they are a little different than the average CZ 75.
