This is actually amazing to some that you can hit a man sized target well with out "aiming".
It's like when you take that shot with the beer bottle with out hesitation to the trash can and it goes right in.....then the focused or shots you try miss by a,mile.
Often you need to just let your mind do it. Once YOU start thinking things don't go as well...
It's on the lines of "lucky" shot.
Practice is key....I will chime in to say start close and work your way out. Have goals and do not advance until you make them...
My point is that raising the gun to your eye level, even while not using the sights but using target focus instead, is just as fast as hip shooting, but more accurate.
