As a young man,, and enjoying western movies & the concept of hip shooting,, I used to do a lot of it. I got pretty good. I mean,, why not? John Wayne & Clint Eastwood could do it!
But it was long before I had anybody teach me about serious longer range handgun shooting. You know,, where you actually use the sights,,, correctly!
Well, I developed a motor memory skill of focusing on the target, and NOT my sights. It caused me a lot of headaches trying to become an accurate handgunner at any real distance. My eyes kept wanting to focus on the target, causing me accuracy issues.
Retraining my motor memory skills, and such after a few decades of doing it improperly has been tough.
But I agree that it's a ton of fun to hip shoot, or just instinct shoot!
