The thing to remember about NYPD guns is they really aren't the NYPD's guns. Guns are the personal property of the individual officer. So if tomorrow they decide the 3914DAO is no longer authorized, I can keep mine because I bought it myself. I'm no longer authorized to carry it, but I can keep it for recreational purposes. So it's entirely possible and even common for unauthorized guns to stay in its original form in the possession of an officer.
