and training purposes. However, after the outbreak of war, supply exigencies and the need to order readily available and compatible ammunition, such as the .38 S&W Super Police, from U.S. sources forced British authorities to issue both the .38/200 Mk I and MkII/IIz cartridges interchangeably to forces deploying for combat. The Cartridge S.A. Ball Revolver .380 inch Mark II and Cartridge S.A. Ball Revolver .380 inch Mark IIz cartridge were theoretically phased out of British service in 1963, when the 9×19mm semi-automatic Browning Hi-Power pistol was finally issued to most British and Commonwealth forces. Variants The .38 Colt New Police was Colt's Manufacturing Company's proprietary name for what was essentially the .38 S&W with a flat-nosed bullet. The U.S. .38 S&W Super Police cartridge was nearly identical to the British .38/200 Mk I, using a lead alloy bullet with a muzzle velocity of and a muzzle energy of , and was supplied by several U.S. manufacturers to the British government as equivalent to the Mk I loading. MKE 9.65 mm Normal (9.2×23mmR (.38 Smith & Wesson)) cartridge has a lead-antimony alloy bullet with a gilding-metal full metal jacket and a Boxer-primed brass case. The "normal" designation differentiates it from their 9.65mm Special (9.1×29mmR (.38 Special)) round. It uses the 9.65 mm (.38-caliber) nominal bore rather than its 9.2 mm (.361-caliber) actual bore. It has a muzzle velocity of . Current status The .380 Mk IIz is still produced by the Ordnance Factory Board in India, for use in revolvers. Commercially, only Ruger makes limited runs of revolvers in this caliber for overseas sales, and only a few companies still manufacture ammunition. Most of those that do so offer it in only a lead round nose bullet, though Fiocchi still markets full metal jacket bullet rounds. Some companies, such as Buffalo Bore, manufacture several different types of ammunition for self-defense and/or hunting.
