Unfortunately there's quite a price difference between the white dot sights and the front night sight. Trijicon can't afford to give you 3 others...or they'd have to triple the price!
I think the idea is that "there can be only one" right height. If you think the height is off, then you'll have to compensate by changing how you hold and aim the gun. Let's face it - most manufacturers don't offer 4 different sights. They make one...if you don't like it, you have to buy from someone else. Most of the time, though, the aftermarket guys make theirs the same size as the OEM. I think Walther spoils us by having so many options!
