The Beretta Cheetah, also known with its original model name of "Series 80", is a line of compact blowback operated semi-automatic pistols designed and manufactured by Beretta of Italy. They were introduced in 1976 and include models in .32 ACP (Model 81), .380 ACP (9 mm Short) (Model 84, 85 and 86) and .22 LR (Model 87).
Model 84 is chambered for the .380 ACP (9 mm Short) cartridge. It has a double stacked magazine with 13 round capacity. Model 84 has a four inch barrel, and has an ambidextrous frame-mounted De-cock/safety. The frame is alloy. It is available in both black and satin nickel finishes, with plastic or wood grips.
Improvements to the original Cheetah resulted in the BB suffix (e.g. 81BB). These models have a loaded chamber indicator and firing pin safety. Later BB models replaced the original wooden grips with black plastic grips.
Current production models are in the FS configuration (e.g. 81FS). This includes a restyled trigger guard (notably square shaped) similar in appearance to current Beretta 92 models that allow for a finger hold on the front of the trigger guard. Previous models have a rounded trigger guard. A decocker was integrated into the safety; when the safety-lever is manipulated to safe, the hammer is also lowered.
In general, all these pistols are blowback operated, hammer fired guns. Ambidextrous safety is mounted on the frame and disconnects the trigger from the sear and locks the slide when engaged. Slides are of familiar Beretta opent-top pattern, and overall shape of these guns is very similar to famous Beretta 92 pistol. Frames are made from ligh alloy, slides are steel. All centerfire pistols of this family featured fixed sights, dovetailed into the slide. These guns can be found in blued or nickel finish, with plastick or wooden grip panels.
