...it's not me, haters. :tongueout: Quack shot it and was about 3" high as well. He had the 9mm Springfield MilSpec (I shot it and was dead on) and his STI Tac and you could see that this is definitely the tall 10-8 rear on the EMP when side by side. I was planning on switching out the front anyway since I don't like the factory tritium SA uses on the EMP. Going to switch to a taller front.....and also going to try out a brass bead front with the 10-8 rear setup.
