For those who are wondering why a judge would order Chicago PD to stop allowing P320's for duty use, here's the explanation - it started with a suit brought by the police union:
⚖️ Federal Judge Orders Cops to Stop Carrying Sig P320
Liberty Doll
As I understand it, CPD had entered into some consent agreement involving duty pistols some years ago and this court had oversight. I don't live close to Chicago anymore so I'm not current on the details. But it sure is interesting.
