Here's a way to practice hip "aiming" without shooting. Stand about 4 feet from a full length mirror. While you look at your image, concentrate on one of the eyes and draw your revolver (unloaded, of course). Point it at the eye of your image you are focusing on. when it feels right, look at the revolver your image is holding. If you are on target you can see the sights are lined up on your eye, the front sight in the rear sight as it should be, only backwards. In some revolvers with a hammer mounted firing pin, you can see the firing pin hole down the barrel of the revolver your image is holding. When the hole is centered in the bore, you are on target. If you are off target, move your revolver while you watch the image's revolver until you can see the sights are lined up on it. You are now accurately, from the hip, zeroed in on the eye of your image. Hold it there for a time to allow your brain to do it's thing, then start again from the holster. You are building muscle memory allowing you to feel your aim going to where you are looking. It works.
