For those who seem to think you cant make good, or at least, decent hits, without using the sights, much beyond contact distance, anyway. I shot this target this morning, with a Glock 19, at 10 yards (yards, not feet). That target has around 70 rounds in it, and all were fired at that distance. About 2 mags worth in the head were "aimed" double/triple taps. The rest were shot without using the sights, and most were at least a double tap. All were shot/started from a SUL ready.
Basically, for all the "unaimed" shots, I pushed the gun straight out from SUL, at about nipple height, maybe a little higher, and my focus was on the target, where I wanted the rounds to go. I didnt consciously see the gun or the sights while I was shooting.
Im in no way saying you shouldnt use your sights, and I normally do, especially once Im past 10 yards or so. What I am saying is, its not at all hard to make "good" hits, where your looking, with no sights, and even while moving, if you make it part of your regular practice. I practice both, every time Im out.
If you dont/havent/never practice it, well, yea, I guess your results will probably not be all that great. Then again, same can be said for your "aimed" fire.
