I have a couple good friends that i shoot with, all LEO's.. 40 S&W seems to be the choice.. I know a few choice LEO's that caryy the 1911's in 45.
When doing my job.. I carried the .40 for a long time.. Ive recently upgraded to a 45.
talked to a county guy yesterday.. he carries the .40 "hornady tap" rounds - on issue from his department.
A few months back.. there was an attempted bank robbery in centralia, I don't mean to revive an old issue. Just making a point here.
Officer shoots, and hits BG not once.. but twice. with his 9mm . BG gets in a taxi, and heads up north!
Word on the street is...that officer upgraded to a .40 or.45 cal.
