Colt's Early Automatic Pistols John Browning's .38 ACPs preceded the familiar Government Model by a decade and were America's "magnums" of the day.

By the time Colt ceased production of the gun in the 1870s, it had churned out more than 215,000 Old Model Navies for the American market, plus another 40,000 for the British market.
