The Tranter revolver was a double-action cap & ball revolver invented around 1856 by English firearms designer William Tranter (1816–1890). Originally operated with a special dual-trigger mechanism (one to rotate the cylinder and cock the gun, a second to fire it) later models employed a single-trigger mechanism much the same as that found in the contemporary Beaumont–Adams revolver.

Early Tranter revolvers were generally versions of the various Robert Adams-designed revolver models, of which Tranter had produced in excess of 8000 revolvers by 1853. The first model of his own design used the frame of an Adams-type revolver, with a modification in the mechanism which he had jointly developed with James Kerr. The first model was sold under the name Tranter-Adams-Kerr.

The Tranter revolver was a "solid-frame" design, very similar in appearance to the Beaumont–Adams revolver. Over the course of the 3 models Tranter developed, the only significant change was to the attachment of the ramrod- In the first model it was detachable, on the second model it was attached to the frame by a hook on the fixed barrel, and in the third model (1856) it was attached to the barrel by a screw.

On the double-trigger Tranter revolvers, a second trigger below the trigger guard served to cock the gun. The hammer on this model had no spur and therefore could not be cocked with the thumb. To fire the weapon in the single-action mode, one had to first press the lower trigger, which would pull the hammer back and rotate the cylinder; at this point one could fire the gun with a light pull on the upper trigger. To fire more rapidly, one could pull both triggers simultaneously, making it a double-action weapon.

With the beginning of the American Civil War, the demands for foreign weapons in the Confederate States of America increased, as the Confederacy no longer had access to the weapons factories in the North and had almost no local small-arms manufacturing capability of their own. At the outbreak of the war, Tranter had a contract with the importing firm Hyde & Goodrich in New Orleans to import and distribute his revolvers commercially. Following the outbreak of the Civil War, Hyde and Goodrich dissolved their partnership, and its successors, Thomas, Griswold & Company, and A. B. Griswold & Company, continued to distribute Tranter's guns.
