The Crosman Model 1322 ''Medalist .22 Caliber Pellet Air Pistol'' was a single-shot, bolt-action loading, pneumatic pump-action .22-caliber air pistol, featuring a button-rifled 10.1-in. (256 mm) steel barrel and checkered plastic grips.〔''Crosman'', Field & Stream Magazine, Vol. 82 No. 1 (May 1977), p. 119〕〔Crosman AirGuns, Field & Stream Magazine, November 1978, p. 121〕 The 1322 was introduced in 1977 by Crosman as a general-purpose air pistol for target practice and small game hunting. It was in production, in three separate manufacturing versions, until 2004, when it was discontinued from sale in the U.S.A. In 2012 the gun has been reintroduced by Crosman. ==Design and Operation== The Model 1322 is a pneumatic pump-action air pistol utilizing .22 (5.5 mm) caliber lead pellets. The pistol's integral pump lever mechanism is located underneath the barrel, integral to the forearm. This pump lever is cycled a variable number of times (up to a maximum of ten strokes) to store increasingly pressurized air in a chamber. When the trigger is activated, an air valve dumps the pressurized air into a transfer port integral to the breech, discharging the pellet from the barrel. According to the manufacturer, a maximum velocity of up to was achievable with ten pump strokes, using standard 14.3-grain .22 pellets.〔Crosman AirGuns, ''Crosman 1322 Medalist Owners Manual'', p. 18〕〔Crosman AirGuns, ''Think Of It As A Rifle You Shoot With One Hand'', Popular Mechanics, Vol. 154 No. 1 (July 1980), p. 139: Early Crosman advertisements listed a muzzle velocity of .〕 The Model 1322 features fully adjustable square notch rear and front fixed blade sights.〔''Crosman AirGuns'', Field & Stream Magazine, November 1978, p. 121〕 The Model 1322 was a development of the earlier Crosman ''Model 1300 Medalist II'' in .22 caliber, produced from 1970-1976. The Model 1322 was first introduced in 1977, and was produced over its lifetime in three distinct variants: ''Type I'', 1977–81, ''Type II'', made from 1978-1996, and ''Type III'', 1998-2004. ''Type I'' featured a sliding metal breech cover, manual cocking using a three-ring external cocking knob, and a steel breech.〔''Crosman'', Field & Stream Magazine, Vol. 82 No. 1 (May 1977), p. 119: The Model 1322 used a solid zinc grip frame.〕 The ''Type II'' adopted a plastic breech in place of the original steel version. The ''Type III'' dropped the external cocking knob and breech cover of prior types in favor of a brass bolt action mechanism that integrated loading and cocking functions.〔''(Crosman Products Dates of Manufacture )'', retrieved 17 April 2011〕 While the Model 1322 was not designed as a competition-level target airgun, its long rifled barrel makes the Model 1322 surprisingly accurate for a mass-produced air pistol. Its accuracy can be further enhanced with precision sights and other modifications. *Crosman reintroduced the Model 1322 in 2012. It comes with black grips and is now available from many retailers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Crosman 1322」の詳細全文を読む スポンサード リンク
