The term “derringer” derives from a misspelling of the last name of Henry Deringer, a famous maker of small pocket pistols in the 1800s. Deringer’s popular design was copied by gun makers across the globe, and “derringer” soon became a generic term for any pocket pistol. Derringers, which are usually the smallest handguns of a given caliber, are especially popular among women because they can be easily concealed in a purse or stocking.
