"You weren't paying attention. It wasn't "one dude". There have been multiple shootings in the county I live in and NOT ONE was a one shot stop."
So, what can we draw from that?
Anything concrete?
Nope.
What we can SPECULATE, however, is broad and diverse.
Speculation 1.
The .40 is fine. It's the cops in your county who can't shoot worth a damn.
Speculation 2.
Instead of every shot from ever cop in your county being either center of mass/center of central nervous system hits, it could be that those hits are, at best, marginal (stomach), or at best, peripheral (legs, hands). See Speculation 1.
Speculation 3.
The ammunition being provided to the cops in your county isn't optimal, and thus is handicapping the officers during shootings.
Those are three possible specualtions. There are a lot more. But since your messages are pretty devoid of actal facts, there's not much more to go on other than speculation.
But, now for some facts.
Fact 1.
The results obtained by the officers in your county are but a small fraction of shooting incidents involving the .40 S&W.
Fact 2.
The .40, with well designed ammunition and being fired by well trained individuals who obtain solid hits, has developed a very solid reputation as an effective handgun round.
Fact 3.
Lacking any more facts, the ONLY, and I mean ONLY, conclusions you can draw from your county's experience is... nothing conclusive.
Fact 5.
Dismissing the .40 S&W based solely on the experience of your county's officers and ignoring the bulk of the information that is readily available is silly.
