so, i go into business with this guy and things are going great. making some money. life is good. down the road, i told him i was in need of another carry pistol and he gives me a beretta 84fs as a gift for christmas. really nice. later on i find out he is cheating customers and coming on to my wife so i break of the partnership clean. nobody owes anybody anything. some time passes and he shows up and wants HIS pistol back. i told him i only had guns that were mine and had nothing of his. it was a gift. mine. no bill of sale on this because i figured it was a gift. my question would be does he have any legal ground to making me give my pistol to him. any constructive input would be appreciated.
