== new foresights were issued to compensate ==The Enfield No.2 Mk I was designed for use with the Cartridge S.A. Ball Revolver .380 inch Mk. I and Mk. Iz, a deviation of the .38 Smith & Wesson cartridge, also known as the .38/200. It had a 200 gr (13 g). unjacketed round-nose, lead bullet of .359 inch diameter that developed a muzzle velocity of 620–650 ft/s (190–200 m/s). Just prior to the outbreak of the Second World War, British authorities became concerned that the soft unjacketed lead bullet used in the 380/200 might be considered as violating the Hague Convention of 1899 governing deforming or 'explosive bullets'. A new .38 loading was introduced for use in combat utilizing a 178-grain (11.5 g), gilding-metal-jacketed lead bullet; new foresights were issued to compensate for the new cartridge's ballistics and change to the point of aim.The new cartridge was accepted into Commonwealth Service as "Cartridge, Pistol, .380 Mk IIz", firing a 178 - 180 grain (11.7 g) full metal jacket round-nose bullet. The 380/200 Mk I lead bullet cartridge was continued in service, originally restricted to training and marksmanship practice.However, after the outbreak of war, supply exigencies forced British authorities to use both the 380/200 Mk I and the .380 Mk IIz loadings interchangeably in combat. U.S. ammunition manufacturers such as Winchester-Western supplied 380/200 Mk I cartridges to British forces throughout the war.
