I would use caution with this idea!
There are some cops out there who really value their duty gun......some of them might even start to tell you stories about where and when it was purchased and what a good luck charm it has been and the memories associated with it. One lucky fellow I know actually carries a Glock 17 that was purchased for him by his girlfriend (now his wife) while they were dating. Competitive use, schools, and concealed carry would likely make its way into the conversation.
This could be very time consuming if you are on your way to work.
