Ammunition, Missiles and precision weapons

A rimless, straight-taper case which may be of brass, aluminium, or steel, Boxer or Berdan primed. Originally developed by John Browning in 1905, this cartridge was approved by the US Ordnance in 1911 along with the Colt pistol. It was the standard military pistol cartridge in the USA until the adoption of the 9 × 19 mm Parabellum round in 1985 and is still in general use. An enormous variety of bullets has been developed for this round, but the standard military loading has always been a 15.16 g lead-cored, full

metal jacket round-nosed type. It continues as the standard pistol calibre for US special operations forces, particularly in its +P loading. The cartridge is also used by many US police agencies. The 0.45 ACP was adopted by Norway and several Central and South American countries and has been used by the UK and Commonwealth forces at various times. A popular commercial round, weapons continue to be made for it in many countries. Despite adoption of the 9 × 19 mm cartridge by the US military, American special operations forces continue to use pistols in this calibre. Compatible platforms include colt M1911 , M1911A1 semi-automatic pistols and pistols based on the original M1911 design; Smith & Wesson, Star, Obregon, Hafdasa, Heckler and Koch and many other pistols; Smith & Wesson and Colt M1917 revolvers; Thompson, Reising, M2, M3 and M3A1 sub-machine guns; De Lisle silent carbine; other police carbines.
