Quote. I've talked to a few old-timer cops, including one that taught my CCW class. Without a doubt, they'd all choose a .45 like the SIG P220 over a 9mm.
Considering that concealability isn't important, I can't say I'd argue with that choice.
Why. ? Have they shot someone with a 9mm and it was not effective. Or do they believe the myth that a .45 will knock someone of their feet.
It would make you wonder how the rest of the world is happy with the 9mm. There is a world outside the united states. Maybe the police in the USA are right and the rest of the world is wrong.
