On 9 September 2014, Jin won the 50 metre pistol gold medal at the 2014 World Shooting Championships after shooting 583 points out of possible 600 in the qualification, thereby breaking the 34-year-old World Record of 581 points set by Soviet Aleksandr Melentyev at the 1980 Summer Olympics. In doing so, Jin also set several milestones not seen in 50-metre pistol since the current quadrennial intervals between the world championships were established after the 1954 World Championships; World championships were previously held annually until 1931 (with exceptions) then biennially until 1954. He became the first shooter since 1952 (and fourth overall) to have won three world-level championships (Olympics and world championships) and the first since the 1956 Summer Olympics (fourth overall) to simultaneously hold the Olympic and World titles in the discipline. He also became the second 50-metre pistol shooter (after Ragnar Skanåker in 1993) to have won the Olympics, the world championships and the World Cup Final. Two days later he also won the 10 metre air pistol gold medal at the same world championships.
