Editing Revolver (section)

===Other===
In the era of cap-and-ball revolvers in the mid 19th century, two revolver models, the English Tranter and the American Savage "Figure Eight", used a method whereby the hammer was cocked by the shooter's middle finger pulling on a second trigger below the main trigger.

Iver Johnson made an unusual model from 1940 to 1947 called the ''Trigger Cocking Double Action''. If the hammer was down, pulling the trigger would cock the hammer. If the trigger was pulled with the hammer cocked, it would then fire. This meant that to fire the revolver from a hammer down state, the trigger must be pulled twice.<ref>{{cite book |author=S. P.

This is similar to the action of the "sytème Triple action" patented by Eugène Lefaucheux in French patent number 55784 on September 27, 1862 for pinfire revolvers produced in the 1860's in France. The Lefaucheux Triple Action can be used in single action by cocking the hammer with the thumb, or in double action with a long pull on the trigger, or the hammer can be cocked by a pull on the trigger, then allowing one to shoot in single action.{{Citation needed|date=August 2023}}
