police and civilians for being reliable and concealable. They would remain the standard issue police pistol for much of Europe well into the 1970s. During World War II, they were issued to the German military, including the Luftwaffe. The Smith & Wesson Model 36 was designed in the era just after World War II, when Smith & Wesson stopped producing war materials and resumed normal production. For the Model 36, they designed a small concealable 5-shot revolver with a 2" barrel that could fire the more powerful .38 Special cartridge. Since the older I-frame was not able to handle this load, a new frame was designed, which became the J-frame. The new design was introduced at the International Association of Chiefs of Police (IACP) convention in 1950 and was favorably received. A vote was held to name the new revolver, and the name "Chief's Special" won. A -barreled version design went into production immediately, due to high demand. It was available in either a blued or nickel-plated finish. It was produced as the "Chief's Special" until 1957 when it then became the Model 36. Smith & Wesson would also introduce the J-frame Smith & Wesson Centennial (hammerless models) and Smith & Wesson Bodyguard (shrouded hammer) models. The Makarov pistol was introduced in 1951. As the new standard issue sidearm for all Soviet military, police, and security forces it was intended to be carried both holstered and concealed. It can still be found in front-line service with the Russian military, police, and security forces. The Makarov is a medium-size, 9-shot, 9x18mm, blowback-operated, all-steel construction pistol. The general layout and field-strip procedure of the Makarov pistol is similar to that of the Walther PP. The 9×18mm cartridge is a practical cartridge in blowback-operated pistols; producing a respectable level of energy from a gun of moderate weight and size. Other, more powerful cartridges have been used in blowback pistol designs, but the Makarov is widely regarded as particularly well-balanced in its design elements. The Beretta 950s are 9-shot, .25 ACP (Jetfire) or .22 Short (Minx) semi-automatic pistols introduced by Beretta in 1952. They build on a long line of small and compact pocket pistols manufactured by Beretta. They are very simple and reliable blowback operated pistols with a single action trigger mechanism. Their frames are made out of aluminum alloy, their slides and barrels are carbon steel. They feature a unique tip-up barrel
