“Mr. Clapp did not mention the dominant eye under aiming (in his article about the ABCs of Pistol Shooting). Should I learn to shoot with both eyes open for rapid target acquisition?”

Thanks for writing. This is a good question. Simply stated, the answer is yes, but not necessarily for rapid target acquisition.
If you are using both eyes, you are getting a form of binocular vision. Also, the muscles of your face are much more relaxed and you see more. However, many people—including this writer—just can’t seem to align the sights with both eyes open, so they close one eye and focus on the front sight much better.
Also, the question of the dominant eye can be addressed here. Most humans have one eye that works better than the other. Regardless of which hand you use to grasp the pistol, use the dominant eye to align the sights. This is true even if it results in a so-called “cross-eyed” situation, as right-hand, left-eye. I do that every day. Hope this helps.
