Chuck has either "been there and done that," or he is one hell of a liar. I always enjoyed his articles, and had no doubts about his credibility.
He is a proponent of the 1911A1 and the 230 grain hardball load.
Chuck Taylor's ASAA -Stopping Power
"Were I to "play the percentages," or base my opinion on a more narrow examination such as (for example) a review of the files of the law enforcement agencies with which I have been associated or draw from my own personal experiences alone, I could legitimately state that .45 ACP 230 gr. "hardball" fired from a M-1911 Colt auto, is 100% effective!
How? Simple -- in all of the departmental shootings in which it was used, it worked. And because in five of the seven pistol fights in which I have been a participant, I used a .45 with ball ammo -- and it worked. I won all five with my first shot, my opponent collapsing before I could fire again. Five center hits, five one-shot stops, five DOS (dead on the scene)."
That's my man. Apparently, he is still holding classes.
