The British Bull Dog was a popular type of solid-frame pocket revolver introduced by Philip Webley & Son of Birmingham, England, in 1872, and subsequently copied by gunmakers in continental Europe and the United States.

[4] A version made by Webley, but finished by Belfast-based gunmaker, Joseph Braddell, known as the Ulster Bull Dog, used a longer grip frame than the standard, making the revolver easier to control and shoot.

[2] The British Bulldog was more popular among civilians during the conquest of the American West in the nineteenth century than more famous revolvers made by Colt's Manufacturing Company or Smith & Wesson.

Charles J. Guiteau used a .442 Webley British Bulldog revolver to assassinate United States President James A. Garfield at the Baltimore and Potomac Railroad Station in Washington, D.C., on 2 July 1881.

Guiteau reportedly wanted a British Bulldog revolver with ivory grips instead of wooden ones, as he believed they would look nicer when the gun was displayed in a museum,[9] but decided not to spend the extra US$1 (equal to $31.57 today) that the ivory-gripped model would have cost.
