What model Glock are these on? When I was entertaining buying some of these sights for my G34, I found various posts talking about different bullet weights affecting the front sight height.
All Glock model Warren Tactical and Sevigny sights are designed for a twenty yard point of aim/point of impact. Warren Tactical's recommendation is to use the .245 tall front with the Glock 24, 34, 35, and other long slide guns and the .215 for all other Glock models. Remember that Glocks and M&Ps are production guns, so there could be slight variations in each of them, and point of aim/point of impact is further affected by ammo differences, bullet weight differences, shooter tendencies, etc.
