"Big Iron" is a country ballad by Marty Robbins, originally released as an album track on Gunfighter Ballads and Trail Songs in September 1959, then as a single in February 1960. Members of the Western Writers of America chose it as one of the Top 100 Western songs of all time.
It tells the story of an Arizona Ranger's duel with an outlaw named Texas Red in the "town of Agua Fria". The town predicts the death of the Ranger (Texas Red had already killed 20 men), but the Ranger kills Texas Red with the swiftness of the "big iron on his hip." This term refers to the gun the Ranger carries.
The song is also featured in the video game Fallout: New Vegas on the in-game radio.
The Ranger's "Big Iron" actually existed. It was a one off custom handgun chambered in .45 Colt and featured a Great Western copy of the Colt Single Action Army frame, Colt 1860 Army backstrap, grip frame and grips and a cut down 9 1/2" Marlin rifle barrel. Marty Robbins saw it in Andy Anderson's famed North Hollywood gun shop in the late 1950s and wrote the song around it. Its current whereabouts are unknown.
