Just purchased a Gen 5 34. It has the factory Glock sights. I want to put fiber optic sights in front and plain black in rear. What hight should I get in the front sight. And do I get a specific hight for a specific bullet weight. The Dawson web site has the front sight height at .215. Doing some research online, people say they are running either .235 or .245. I am confused.
