What handgun cartridge designed by John Browning in 1905, for use in his prototype Colt semi-automatic pistol, is chambered in a third-generation semi-automatic pistol from Smith & Wesson's 4500 series of handguns?
Smith &amp; Wesson Model 4506 The Smith & Wesson Model 4506 is a third-generation semi-automatic pistol from Smith & Wesson's 4500 series of handguns. The 4506 is chambered for the .45 ACP cartridge and, with the purchase of special springs, the stronger .45 Super. It is constructed almost entirely from stainless steel and is thus extremely resistant to harsh weather conditions. The 4506 is a traditional double-action/single-action pistol. The first shot is fired in double-action mode. Each subsequent shot is fired single-action mode. It features one-piece Xenoy wrap-around grips with either a curved or straight back strap. The 4506 was produced from 1988 to 1999.
Sport pistol A sport pistol or standard pistol is a type of handgun used in several shooting sports, including the Olympic 25 metre pistol event and 25 metre standard pistol. Since 2005, the 25 metre rapid fire pistol rules also require the use of sport pistols, with a few extra requirements. Other sports to make use of this gun are women's 25 metre military rapid fire pistol, bullseye (in one of its three stages), and a variety of other national shooting sports.
