Isn't LA mainly 9mm?
Here in Chesapeake VA they use Beretta 92s
I know that the Dept of Homeland Defence has ordered a whole bunch of H&K P2000s and P2000SKs in .40 and 9mm. I'm guessing that the SKs will be the 9mm variety but I don't know which departments specifically will be issued with them.
NC SP shoot .357 in their Berettas.
