Paine entered all three of the pistol events at the 1896 Games, but actually competed in only one. He, along with his brother Sumner Paine, was disqualified from the rapid fire pistol event for not having the appropriate caliber pistol. Both of the Paines used Colt revolvers, firearms that were far superior to those used by their opponents in the 25 metre military pistol event, John won the event easily, scoring 442 points on 25 hits out of 30 shots, Sumner was not far behind, at 380 points on 23 hits; the third-place finisher, the GreekNikolaos Morakis, scored only 205 points.[5]
Paine then withdrew from the 30 metre free pistol event, citing his desire to not embarrass his Greek hosts.[1] He also said he had an agreement with his brother that whoever won the first event between them would drop out the next event.
