I have a solution.
Sell the gun to me for a dollar. Then you can honestly tell your co-worker that you no longer have the gun and to leave you alone. I'll sign a bill of sale and everything.
When he finally gives up the fight, I'll sell you the gun back (at a
slight mark-up, of course)
Seriously, offer to sell it back to him for twice what you paid for it. If he refuses, tell him to STFU and leave you alone. If he accepts, use the money to fund a replacement purchase. I seriously doubt there was only one of those (whatever it is) made.
