The term was coined by firearms author Robert Shimek, and became popular in American firearm-related magazines during the 1980s by those advocating for their use by police forces. At the time most American police departments were still using revolvers, chambered in calibers such as .38 Special and .357 Magnum.
The simplicity of being able to fire the first shot just by pulling the trigger, a feature of double-action revolvers, combined with the high ammunition capacity (13–18 rounds, more than twice of what a revolver holds), are the "wonderful" features of a wonder-nine.
