The typical carbine is the pistol-caliber carbine. These first appeared soon after metallic cartridges became common. These were developed as "companions" to the popular revolvers of the day, firing the same cartridge but allowing more velocity and accuracy than the revolver. These were carried by cowboys, lawmen, and others in the Old West. The classic combination would be a Winchester lever-action carbine and a Colt Single Action Army revolver in .44-40 or .38-40. During the 20th century, this trend continued with more modern and powerful smokeless revolver cartridges, in the form of Winchester and Marlin lever action carbines chambered in .38 Special/.357 Magnum and .44 Special/.44 Magnum.
