It seems like all municipalities are moving up to .40’s as standard issue guns. Buddy of mine just started with W. Mifflin and I know they issued him a .40, and I’m almost positive that all Pgh Police are told that the .40 is the “preferred” caliber of the force.
Just the physical size of the casing between the .40 and the 9mm is enough to make me believe the cops need to be carrying those .40
