I have a good friend who is a police officer somewhere near Raleigh, NC. He told me recently that they have switched from the Glock 22 to the Glock 17. I was kind of surprised to hear that. I have never been able to warm up to the .40 S&W myself though. I wouldn't bet money, but I believe he said that their duty ammo was the Winchester Ranger 127 grain +P+. So I am sure that they are using a very good load. He told me that when he first started working there he was issued a brand new model 22 and when they made the switch he was able to buy his model 22 for a very good price.
