Beretta 92

The Beretta 92 (also Beretta 96 and Beretta 98) is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. The Beretta 92 was designed in 1975, and production began in 1976. Many variants in several different calibers continue to be used to the present.
The United States military replaced the .45 ACP M1911A1 pistol in 1985 with the Beretta 92FS, designated as the M9.
History.
The Beretta 92 pistol evolved from earlier Beretta designs, most notably the M1923 and M1951. From the M1923 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 Browning Hi-Power.
Carlo Beretta, Giuseppe Mazzetti and Vittorio Valle, all experienced firearms designers, contributed to the final design in 1975.
Evolution.
92.
Production began in May 1976, and ended in February 1983. Approximately 7,000 units were of the first "step slide" design and 45,000 were of the second "straight slide" type.
92S.
In order to meet requirements of some law enforcement agencies, Beretta modified the Beretta 92 by adding a slide-mounted combined safety and decocking lever, replacing the frame mounted manual thumb safety. This resulted in the 92S, which was adopted by several Italian law enforcement and military units. The magazine release button is at the bottom of the grip as is customary in Europe. This model was produced from 1978 to 1982.
92SB (92S-1).
The 92SB, initially called 92S-1, was specifically designed for the USAF trials (which it won), the model name officially adopted was the 92SB. Features added include a firing pin block (thus the addition of the "B" to the name), ambidextrous safety levers, 3-dot sights, and relocated the magazine release catch from the bottom of the grip to the lower bottom of the trigger guard. The later relocation of the magazine release button means preceding models (92 & 92S) cannot necessarily use later magazines, unless they have notches in both areas.
A compact version with a shortened barrel and slide and 13-round magazine capacity known as the 92SB Compact was manufactured from 1981 to 1991.
92F (92SB-F).
Beretta modified the model 92SB slightly to create the 92SB-F (the "F" added to denote entry of the model in U.S. Government federal testing) by making the following changes:
The French military adopted a modified version of the 92F with a decocking-only lever as the PAMAS G1. These pistols have tellurium in the slide, making the steel brittle and as such only have a service life of approximately 6,000 rounds.
92FS.
The FS has an enlarged hammer pin that fits into a groove on the underside of the slide. The main purpose is to stop the slide from flying off the frame to the rear if it cracks. This was in response to reported defective slides during U.S. military testing.
The 92FS also came in a Centurion model which featured a shorter barrel that just clears its full size frame.
Design.
The Beretta 92's open slide design ensures smooth feeding and ejection of ammunition and allows easy clearing of obstructions. The hard-chromed barrel bore reduces barrel wear and protects it from corrosion. The falling locking block design provides good accuracy and operability with suppressors due to the in-line travel of the barrel. This is in contrast to the complex travel of Browning designed barrels. The magazine release button is reversible with simple field tools. Reversing the magazine release makes left-handed operation much easier.
Increasingly, it has become popular to reduce handgun weight and cost as well as increase corrosion resistance by using polymers. Starting around the year 2000, Beretta began replacing some parts with polymer and polymer coated metal. Polymer parts include the recoil spring guide rod (which is now also fluted), magazine floor plate, magazine follower and the mainspring cap/lanyard loop. Polymer coated metal parts include the left side safety lever, trigger, and magazine release button.
Magazines.
To keep in line with the introduction of laws in some locations restricting magazines that hold more than 10 rounds, Beretta now manufactures magazines that hold fewer than the factory standard 15 rounds. These magazines have heavier crimping (deeper indentations in the side) to reduce the available space while still keeping the same external dimensions and ensuring that these magazines can be used on existing firearms. Beretta also produces 15 round "Sand Resistant" magazines to resolve issues encountered with contractor made magazines, and 17 round magazines included with the A1 models. Both magazines function in earlier 92 series and M9 model pistols.
Italian magazine manufacturer Mec-Gar now produces magazines in blue and nickel finishes with an 18-round capacity, which fit flush in the magazine well on the 92 series. Mec-Gar also produces an extended 20-round blued magazine that protrudes below the frame by . These magazines provide users in unrestricted states with a larger capacity magazine.
Variants.
The Beretta 92 is available in many configurations and models:
93R machine pistol.
The Beretta 93R is a significantly redesigned 92 to provide the option of firing in three-round bursts. It also has a longer ported barrel, heavier slide, fitting for a shoulder stock, a folding forward grip, and an extended magazine. Unlike other Berettas in the 90 series it is single-action only, does not have a decocker, and very few are around today.
Copies.
The Beretta 92 was designed for sports and law enforcement use and, due to its reliability, was accepted by military users in South America and other countries all over the world.
