Hambo, you are spot on with this.
I have long maintained much of the effectiveness attributed to .45 acp back in the day was the result of better shot placement due to the “shootability” of the 1911 rather than the .45 being the hammer of Thor.
As another old school gun guy, former African Professsional hunter Finn Agaard said with regard to dangerous game “shot placement is 90 percent of killing power.”
