That gun probably was a trade-in that someone got cheap, and had it bead blasted

Places like Brinks, along with lots of Corrections agencies and security companies are getting rid of their 64's and 10's. Alot of them are later -5's and up, the one I got was a -8.

Anyone advertising them as "police trade ins" is probably just using that as general terminology, as I doubt there are any Police Agencies that are just now getting rid of 64's.
