I had a pretty good compeditor tell me that the targets were so close that he just used the front sight, and hit them well! From his scores I can only guess that his trick was credible or he was a heck of a good point shooter.
I have tried hip shooting and it's a lot harder than it looks! Point shooting is just a matter of forming a triangle to your stance and doing the same thing EVERY time! Again harder than it looks!
Pratice and repitition is the key.
