The Webley .455in service revolver is among the most powerful top-break revolvers ever produced. First adopted in 1887, in various marques it was the standard-issue service pistol for British and Commonwealth armed forces for nearly fifty years; later versions in .38in calibre went on to see further service in World War II and beyond, as well as in a host of law-enforcement roles around the world into the 1970s. Developed to give British service personnel the ability to incapacitate their opponents in 'small wars' around the globe, the Webley used the formidable – and controversial – .455in cartridge, a variant of which was known as the 'manstopper'. Users found it offered good penetration and excellent stopping power with only mild recoil – indeed, it was rated superior to the US .45 Colt in stopping power. Featuring specially commissioned full-colour artwork and close-up photographs, this is the compelling story of the Webley revolver, the powerful pistol that saw service across the British Empire and throughout two world wars.
