If you are in the repo business, I would guess you have a lawyer. Let HIM deal with contacting the cops. I would not do so directly.

Imagine from the cop's point of view, especially if they do not know you, or know you and do not like you for whatever reason. Guy walks into a station with a gun that turns out to be stolen/used in a crime, who is the most likely suspect? Add in some inconvenient fact, like perhaps the original owner turns out to a neighbor of yours, and/or a vehicle like yours was seen in the area, or the cops manage to trace the relatives of the driver, who all of course swear that poor old whathisname would NEVER engage in criminal activity and always hated guns, blah blah...

Probably they would believe you, but the consequences of becoming a suspect, however temporary, would not be good. (And the cops would have that in mind forever more). Let your lawyer figure this one out. And if everything pans out but the cops are slow in coughing up the gun, the lawyer would be more likely to get it back for you.
