“One Shot Stop” Handgun statistics, and why they’re a load of crap


Monster Hunter Nation

In my last CCW class, I had somebody talk about the famous “Marshall & Sanow One Shot Stop Statistics” and about how this student was going to use a 97% round instead of a 92% round. 


Okay, if you aren’t familiar with these, basically these two guys, Marshall & Sanow, supposedly looked at a ton of actual shootings, where people had been shot once in the torso with a bullet, and then they measured what percentage of those resulted in an immediate stop, i.e. immediate cessation of hostile action.


Then they published their work, and all bullets were rated.  Immediately, people who were not given to critical thinking, accepted these percentages as gospel, and you could hear people arguing at gunshows and on the interweb about how they’re more tactically saavy because their handgun load was a 94% stopper, while yours was a meager 82% stopper.
