The Beretta 92FS Inox is a 9x19mm semi-automatic handgun that Burt Gummer dual-wielded in Tremors 2: Aftershocks. It is essentially a Beretta 92FS constructed out of stainless steel with satin finish rather than steel with blued finish.
The Inox models (from the French "inoxidable" meaning non-oxidizing) feature the following parts made in anodized stainless steel with a light bead blasting finish rather than blued carbon 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. The older Italian-made Beretta Inoxes are usually better received than the American-made Inoxes, which feature blued controls, giving them a semi two-tone look.
The Inox models are some of the most popular Berettas and are still produced today.
The pistol is mostly made of metal, and therefore has quite a weight to it, weighing around 33.3 ounces, unlike other polymer-framed pistols, like Glocks. The pistol features a squared crescent-shaped trigger guard for easier aiming, an ambidextrous safety lever located on the slide and an external hammer. The gun's barrel may be the most unique part of the gun, however, as it is exposed, allowing a 180 degree window for a shell to escape, nearly eliminating the possibility of a shell getting jammed in the bolt. The pistol is chambered for 9x19mm parabellum (9mm) rounds in a fifteen round high-capacity magazine. The gun has an effective range of fifty meters and a muzzle velocity of 1,250 feet per second. The blued stainless-steel slide is coated in a corrosion-resistant material called Bruniton.
One of the most interesting and unique features of the Beretta 92 is its exposed barrel, which allows for less of a chance of a jam. Other pistols like the Glock or 1911, have a hidden barrel, cloaked underneath the side, with the ejection port on one side of the gun. This allows for an easy jam. The Beretta 92's exposed barrel allows for easy cooling as well and gives it a futuristic appearance. The Isreali Desert Eagle large caliber pistol also features this exposed slide feature. Both pistols also feature the barrel locked in place, unlike most other pistol barrels, which are not held down and can move very easily. When the slide locks back, the barrel is held in place by a loop on the frame, so it won't move and risk the possibility of falling apart. The exposed and locked barrel is one of the most attractive features about this gun to veteran and beginning shooters.
The 92FS has been tested by the military and has fired 168,000 rounds without a malfunction. The average 92 can fire over 35,000 rounds before the slide stops working properly.
