In 1889 Colt introduced the world's first double action, swing-out cylinder revolver. This design was so effective and strong, it became the standard for all double action designs that followed.
The 1889 was named the New Navy Model of 1889. When the design was also bought by the Army in 1892 the name was changed to the Colt New Army & Navy Model.
Following standard Colt practice, the 1889 was quickly followed up by improved versions each with it's own model number as the Models 1894, 1895, 1896, 1901, and 1903.
