The mixed (or "open") ISSF 50 meter pistol was one of the seven sport shooting events at the 1980 Summer Olympics. There were 33 competitors from 19 nations. Nations had been limited to two shooters each since the 1952 Games. The gold medal was won by Aleksandr Melentyev of the Soviet Union who broke the world record with 581 points. It was the Soviet Union's third victory in the event, second-most behind the United States at four. Melentyev defeated Harald Vollmar of East Germany by 13 points. For Vollmar this was his third Olympic medal in the same event, having won silver at 1976 Montreal and bronze at 1968 Mexico City. Vollmar was the first man to win at least three medals in the free pistol. Lyubcho Dyakov's bronze was Bulgaria's first medal in the event.
