The Beretta 92 (also Beretta 96 and Beretta 98) is a series of semi-automatic pistols. he 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. Perhaps the Model 92's two most important advanced design features appeared on its immediate predecessor, the 1974 .380 caliber Model 84. The Inox models feature the following parts made in stainless steel: the barrel, the slide (including the extractor, the safety and the right-side manual safety lever), the trigger (and trigger pin), and slide stop lever.
