Tranter Fourth Model
William Tranter · Revolver · Discontinued · 1856
Also known as: Tranter 4th Model, Tranter Fourth Model Single-Trigger Revolver, Tranter Single-Trigger Revolver
Overview
The Tranter Fourth Model is a British .442 (54-bore) percussion cap-and-ball revolver designed by Birmingham gunmaker William Tranter and introduced in 1856. Unlike Tranter's earlier double-trigger designs, the Fourth Model used a conventional single trigger driving what is today called double-action lockwork, allowing the firer to either cock and fire with one long pull or thumb-cock the hammer for a lighter, more deliberate release. Built on a solid frame machined from a single forging with an octagonal barrel, a five-shot cylinder, and a rammer-type loading lever, it was a popular private-purchase sidearm for British officers and saw notable use by both Confederate and Union forces during the American Civil War.

Notes
Chambered for the .442 (54-bore) round ball, roughly equivalent in bore to the Colt Army revolver. The Fourth Model simplified Tranter's signature dual-trigger mechanism into a single conventional trigger while retaining the strong solid-frame construction.
Background
Tranter revolvers were carried by several noted Confederate officers, with documented ownership attributed to cavalry generals such as J.E.B. Stuart and John Hunt Morgan.
