Although I carry with one in the chamber and a few more in the magazine Mr. Pincus really doesn't explain why carrying empty is bad. Rather he asserts and makes pronouncements that not carrying hot is stupid. A good, if not the best, reason for carrying hot is the possibility that you get caught in condition white and your weak hand or arm is injured and you can not rack the weapon in a timely manner.
People who practice the technique of drawing and racking are probably less than a half-second slower, if that and I do not really know if they are slower, than those who carry one in the chamber. Most shooting scenarios involve much more time than a half-second preparation for a lethal encounter.
The cultural bias of asserting our training methods as superior to other techniques is worrisome. Empirical testing and comparison would be the way to resolve some of the arguments for and against both techniques. Ingrained cultural biases can get you killed...it leads to rejecting out of hand alternative ways of viewing and doing things.
I doubt, that anyone here would say that the fellow in this video is at any disadvantage in drawing and firing - he certainly isn't carrying unloaded! Watch carefully, in the first part of the video he shoots with one hand- which is likely how most of us would shoot in a self-defense close up in your face situation. In the second part of the demonstration he uses the two handed hold.
