Improve your handgun shooting speed and accuracy by focusing on the front sight and mastering the flash sight picture. Peter Lessler explains how.

The two most important components of sight use are to focus the eyes on the front sight and then verify the alignment between front and rear sights. The eyes can only focus in one distance plane at one point, and the front sight, rear sight, and target will all be at different distances from the eyes. The reason we pick the front sight as our focus object is that this little stub of metal tells us where the gun is aiming.

When we focus on the target, the front and rear sights will both be blurry. In this case, a small misalignment of the gun (which would be visible as sight misalignment) will not be noticed, and the gun will be looking along a different line of sight than our eyes are looking.

It does not take much of an angular misalignment in the gun barrel versus our eyesight line for the shot to miss the target completely, and since this misalignment represents two diverging lines, the amount of error will grow rapidly with increasing distance to the target.

So, again, we focus on our front sight. This puts the target out of focus, just as it does the rear sights, but, in this case, it’s not a drawback, since just about anything we will be shooting at with an iron-sighted pistol will be easy to see in general.

Any error caused by aiming at a slightly blurry target will only be as big as the blurry edge of the target, which is actually a very small amount of space; truly, it is negligible, especially compared to the potential of the misalignment error allowed by not looking at your sights. So, we focus on the front sight and let the target blur slightly.

How to Increase Speed

Speaking of speed, one goal to work towards is to first achieve with the hands a near-perfect sight alignment with the target as quickly as possible, then visually acquire and judge the correctness of your sight picture as rapidly as can be done. At this point the mind says “good to go” to a good sight picture and commences the trigger squeeze, or says “not yet” to a bad sight picture and corrects it to good one before commencing the trigger squeeze.

This is correct focus. Note the sharp front sight and blurry rear sight and target. This is what you must see for accurate shooting. Click for larger view

This combines two notions. The first is the “flash sight picture,” in which we recognize our sight picture and judge it in a bare instant. The second notion is that the sight picture is the boss, not the trigger finger. In other words, our sight picture is the go/no-go determinant of whether we fire the shot.

No trigger pressure should be applied until our eyes have acquired the sight picture and our brain has approved it. This concept should be burned into the circuitry of your brain: The brain controls the trigger finger based on what the eyes see. This is the basic principle of accurate pistol shooting.
