What is interesting, at least to me, is that I was taught to focus on the front sight, and if I am shooting paper and want a really nice group that is what I do. But I grew up shooting running jack rabbits, always focused on the rabbit, not the sights, and hit a jillion of them. Then when I got into law enforcement, same thing. I focused on the target (after all, when shooting at people you have to KNOW that they have a gun/whatever), and qualified as Master (the highest possible) for thirty years. Ya gotta go with what works for you...
