When the Rollin White patent for metallic cartridges firearms manufacture expired (c. 1870) the Colt's Patent Fire Arms Manufacturing Company started working on its own metallic cartridge revolvers. Thus, after having introduced its first breech-loaders in 1871 (Colt House/Cloverleaf) and 1872 (Colt Open Top), in 1873 Colt launched the Colt Single Action Army along with a new line of pocket revolvers, sorted in five different calibers. Since it was an entirely new line of revolvers this model was called the Colt New Line.[2]
Circa 1884-1886, submerged by the competitors' cheaper imitations and refusing to introduce a lower quality among its own firearms, the Colt company dropped the line and ceased production.[2]

The Colt New Line was chambered and produced as follows.[2]
