Riding Shotgun


The Definition
To sit in the front passenger seat of a vehicle. In modern car culture, it is a position of privilege, usually claimed by shouting the word "Shotgun!" before anyone else. Historically, however, it was a position of extreme high-risk employment.
The Deep Dive
This is a literal piece of "junk knowledge" from the lawless expansion of the American Old West (c. 1850–1880). Before the advent of the armored car, the "Express" stagecoach was the primary way to move gold bullion, payroll, and mail across the frontier.
The "Messenger": A stagecoach was operated by two people. The "Driver" (or "Whip") had both hands occupied with the reins of four to six horses. He couldn't defend the coach if it was ambushed.
The Weapon of Choice: Beside the driver sat a "Messenger"—usually an employee of Wells Fargo or another express company. This person carried a short-barreled, large-gauge shotgun (often a "coach gun").
The Strategy: A rifle was too precise and slow for a bouncing coach, but a shotgun offered a wide "spread" of buckshot. This made it the perfect deterrent for "Road Agents" (bandits) attempting to spook the horses or board the vehicle.
The "Shotgun" Seat: While the person was officially the "Express Messenger," they were colloquially known as the man "riding shotgun." Their sole job was to scan the horizon for trouble and, if necessary, provide the heavy firepower required to keep the "boot" (the storage compartment) from being robbed.
The phrase didn't actually enter the common lexicon for cars until the 1950's. It was popularized by Hollywood Westerns and television shows like Gunsmoke and Stagecoach. Suburban teenagers in post-war America adopted the term to turn the front seat of a Chevy into a "protected" territory of the "co-pilot."
Fast Facts
The "Coach Gun": The classic shotgun used was a double-barreled 10 or 12-gauge with barrels as short as 18 inches, allowing the messenger to swing the weapon quickly in the cramped space of the driver's box.
The "Whip" Contrast: While the man "riding shotgun" had the firepower, the "Whip" (the driver) had the prestige. Driving a six-horse team at full speed through a mountain pass was considered the peak of frontier skill.
The First Print: Interestingly, the exact phrase "riding shotgun" doesn't appear in 19th-century newspapers. The first recorded use of the specific idiom was in a 1919 newspaper article describing the early days of the West, long after the stagecoaches had been replaced by trains.
