Where Does 'Jump the Gun' Come From?

‘Jump the gun’ comes from the world of track and field. Dating back to the early 1900s, this phrase has to do with the fact that the start of the race would be indicated with a gunshot.

In a 1905 publication called Crowther and Ruhl’s Rowing and Track Athletics, the phenomenon is mentioned:

“False starts were rarely penalized, the pistol generally followed immediately on the signal ‘Get set!’ and so shiftless were the starters and officials that ‘beating the pistol’ was one of the tricks which less sportsmanlike runners constantly practiced.” 

An early– and perhaps the earliest– printed example of the idiom shows up in an issue of The Iowa Homestead from 1921. Here we find the following sentence that uses the phrase:

“Give the pigs a good start; jump the gun, so to speak, and get them on a grain ration before weaning time.”

“Runner Cannot “Jump the Gun” Equipped With Ground Plate: Jumping the starting gun in a foot race is impossible with an electrical apparatus demonstrated at the Amateur Athletic Union convention. If the runner lifts his hand prematurely from the pad, electrical contact with the gun is broken, preventing it from being fired.”

“Why did you jump the gun on lumber?”

“Well, because going back to our conversation at lunch because the newspapers were really riding us.”

For a third example, we look to a May 1932 issue of Boys’ Life:

“In practice workouts he was fast enough; he’d stepped the hundred in ten-two this spring. But competition had his goat; with men to beat his nerves went haywire. He’d jump the gun, the starter’d set him back; twice, three times, maybe. By then, he was out of the race. Always the same.”
