Saw a short but interesting video yesterday of a guy wearing armor being shot from 5-6 feet with a 1911 and barely even flinching. Kind of confirms the absence of actual "knock down power" for most normal handguns imo.From the article: "When the FBI swapped back to 9mm, they released an Executive Summary that includes the line, word for word, “Handgun stopping power is simply a myth.” Stopping power was one of the few tactical myths that were believed by a large portion of the gun-buying public. Stopping power was often a nebulous term that would often declare bigger bullets have more stopping power."
On the FBI's switch back to 9mm, I heard one commentator on the subject say that it was likely due to the elapsed time between the switch away from the 9mm. Basically theorizing that the people who made that decision decades ago and so had a vested interest in not looking stupid for making that decision, were finally retired & gone now. IIRC, it was James Yeager talking about it, but not positive on that.
