Without derailing the thread, the red dot really allows the shooter focus on the target, thus maintaining a far wider situational awareness. In addition for all of the folks on here who can no longer see the pistol sights due to deterioration of eyesight they really help. With the advent of dash cams, and a camera on every light pole we have now gathered hundreds of visual testimonies of what the bodies natural reaction is in a dynamic critical incident. We teach along those lines, the bodies instinctive reaction is amazing, the military has pounded muscle memory in our training for years without ever explaining the whys. Free bio lesson here, when stressed the body pulls blood away from the extremities to increase odds of survival. As a direct result, you lose fine motor skills in a high adrenaline situation. So we train over and over to rack slides with weak hand and not utilize the small slide release button with your thumb. In same light the body always crouches when startled again the bodies instinctive method to protect itself by presenting a smaller foot print. We incorporate that in our training as well. You don’t believe in the bodies ability to adapt? I will leave you with this challenge on your red dot, put a piece of electrical tape over the front of your red dot. When shooting with only one eye (why would you?) you have rendered the sight inoperable. Shoot with two eyes open and one eye will see target, one eye will pick up the red dot and your “third” eye will imprint the red dot on your target like the tape is not even there! Much quicker target acquisition than iron sights. Apologies for the length of response but I do love to teach!
