I spent a LOT of time on the range coaching and teaching and was often disappointed in other coaches or instructors when they took the lazy way out and put a paster on the opposite side of the target of the group the shooters were firing and told them to "Hold here" and this will center your group rather than trying to figure out the problem. Most of the issues can be solved with a little work by the coach and the shooter. Sometimes, there is a time constraint and you need to get the shooter qualified, but others it's just laziness.
Let's talk about the issues listed. A couple go by several names.
Low left, about 8'oclock - On your chart, they just say "Tightening the Fingers" We always called that Milking the grip. As in 'Milking a cow." You fire a handgun by squeezing the trigger with
only the trigger finger and grip the handgun with the gripping fingers and thumb. If you squeeze your entire hand, it moves the sights. Try it when dry firing and you will see.
Six O'clock...
Pushing, Anticipating Recoil... also, trying to see the shots hit. This is a big cause of low shots... as the shooter will drop the muzzle of the handgun at the last fraction of the second to SEE the round hit. Follow Through, just like golf, is important in shooting. The hole doesn't disappear if you WAIT to look AFTER the shot is complete. Once the shooter learns this fact and holds the sight picture until the shot is gone... scores improve dramatically. They also have to realize that the bullet is TOO dang fast for them to actually see the shot hit if they are shooting.
Three and Nine O'clock - Trigger Finger -
The trigger needs to be pressed or squeezed straight back... pushing or pulling to one side will move the muzzle off target, especially if you are jerking on the trigger. A smooth steady squeeze to the rear will NOT disturb a good sight picture and result in a good shot.
Eleven, twelve and/or One:
Pushing on the heel of the grip as you shoot, normally to fight recoil. Causes high shots.
LET the gun recoil.
The key to accurate shooting is to relax, concentrate on Sight Picture, sight alignment and trigger control, and enjoy the experience.
