Phil, I don't have a good answer for that. The sights I purchased were standard height. I fitted all parts together and installed the sights. I had no issues With the sights other than small left to right adjustment. The sights were 6 o'clock low after installation. Some people prefer dead on.
If you have major issues of up or down, the barrel or slide may not be fitted correctly, or you could just change your sights. That's a worst case scenario. A good gunsmith could tell you what's wrong with it.
