Understanding Handgun Sights

I've been around the handgun shooting world long enough to see things go back and forth. But the thing is people who teach un-aimed or instinctive fire still will use sights at some distance, and the people who preach always use the sights will still teach some sort of close up un-aimed shooting such as the speed rock. The difference is the distance at which you can hit something without using your sights.

SSG Tom Pike I understand at very close range un-sighted shooting, but some of the stuff I've seen has to do with instinctive shooting at distance. With the potential of rounds hitting bystanders, I don't think I can justify that, at least for me.
I am not saying that there are not individuals that don't shoot instinctively, I am just not one of them.

Maj Robert Thornton - I've seen some instructors say they don't use sights, but they teach to index along the side or corner of the slide, to me that's pretty much using less effective sights. So at some distance they do use sights. I'd like to take those instructors that say they don't use sights and shoot instinctively at a distance, remove the sights from their gun, put a target out at 25 yards, then put their wife on one side of the target and their kid on the other and tell them to shoot the target. I don't think they would feel quite so superior in their instinctive fire ability.

I’m a law enforcement firearms instructor, was a range officer in the army. “Point and shoot” is an effective technique at under 3 rounds in a split second, life or death scenario, but it takes practice and muscle memory.
