The Beretta 92 (also Beretta 96 and Beretta 98) is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. The model 92 was designed in 1972 and production of many variants in different calibers continues today. The United States Armed Forces replaced the Model 1911A1 .45 ACP pistol in 1985 with the military spec Beretta 92F, the M9. Beretta currently produces the pistol in four different configurations (FS, G, D and DS) and four calibers: 9×19mm Parabellum, .40 S&W, 9×21mm IMI and 7.65mm Luger. ==History== The Beretta 92 pistol evolved from earlier Beretta designs, most notably the M1922 and M1951. From the M1922 comes the open slide design, while the alloy frame and locking block barrel (originally from Walther P38) were first used in the M1951. The grip angle and the front sight integrated with the slide were also common to earlier Beretta pistols. What were perhaps the Model 92's two most important advanced design features had first appeared on its immediate predecessor, the 1974 .380 caliber Model 84. These improvements both involved the magazine, which featured direct feed; that is, there was no feed ramp between the magazine and the chamber (a Beretta innovation in pistols). In addition, the magazine was a "double-stacked" design, a feature originally introduced in 1935 on the 9mm FN/Browning "Hi-Power".〔Gangarosa, Gene Jr., "Modern Beretta Firearms", Stoeger Publishing (1994)〕 Carlo Beretta, Giuseppe Mazzetti and Vittorio Valle, all experienced firearms designers, contributed to the final design in 1975.〔(【引用サイトリンク】title=Beretta Web - 92FS 15 years of evolution and success )〕 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「Beretta 92」の詳細全文を読む スポンサード リンク
