tHE PERFECT PISTOL SHOT
In the The Perfect Pistol Shot we examine the destructive influence of over-grip and improper trigger-finger movement on accuracy. While over-grip is the single greatest cause of mischief in marksmanship, trigger-finger error is also a serious problem which goes largely undetected. There are two ways in which the trigger-finger can adversely impact your shooting:
1. Pushing. If you have shots that group perfectly at the bullseye except for being about 2" to the support-side of your aiming point, your trigger finger is using your thumb to leverage the weapon to the support-side. The cure is to lift your thumbs off the weapon when firing. You will immediately notice a 2" shift back to your point of aim.
2. Pulling. Too much finger in the trigger can wrap around the face of the trigger and cause shots to be pulled to the shooting-side. This error is cured by proper trigger placement and lifting the thumbs. Thumbs-up reduces the trigger finger's ability to pull against the firearm but does not cure the shooter error of bad trigger finger placement. In The Perfect Pistol Shot, I explain proper finger placement. Here's a summary:
The reason The Perfect Pistol Shot recommends handgun shooters keep both eyes open is perspective. The human eye is designed to work as part of a pair. Close one eye and the objects in your vision appear to shift. Switch eyes and vision swings an inch or so in the other direction. Triangulating the front sight tip between both eyes' focus ensures a truer positioning of the sights.
Defensive use of the handgun requires situational awareness. Defenders must collect as much second-to-second intelligence as is reasonable. In other words, if you close one eye, you are half-blind to potential danger.
Some shooters have pronounced vision problems that prevent two-eyes open. Obviously, the shooter must adapt to reality but shooting with one eye closed out of habit is a self-imposed handicapping of your shooting ability.
