I have an M&P9 that I will be using for carry. I recently installed a set of XS Big dots and they shot stupid low, even from a rest. During my CCW class, we did some defensive shooting drills and I didnt even use my sights. I just looked over the slide and shot instinctively. I was surprised at how easy it was to shoot this way. Anyway, Im looking for some different sights and Im eyeing the Trijicon HD's. Anyone have exp. with these or other quality night sights. I still target shoot with this gun so accuracy is a must.
