If you're really a "PD DISPATCHER", you probably should ask around the office and ask your LEO friend what's possible and the reason(s) needed to make such inquiries.
Generally, you'd need a law enforcement reason, not a personal reason, to inquire, i.e. an official investigation.
If I had such a firearm, I wouldn't want someone calling me asking if I had it, whether law enforcement or not, without an official need.
Edited to add:
I've come across a few cops who've become emotionally attached to their duty weapon, particularly those who've worked for a department which has had a history of selling the used/retired firearm to its issued owner.
For those LEOs who think they'd want at least an example of the issued firearm, I recommend buying one when it's first issued and hopefully still available brand new.
Later, the department may no longer sell its retired firearms to the issued user and even that specific model may be hard-to-find in an acceptable condition.
