Development History
This handgun is an evolution of the Model 90, the first full-size 9mm Luger pistol made by the Argentine company and introduced in 1989.
In 1994, when the entire Bersa pistol production line was renamed "Thunder", the Model 90 was modified with better functionalities and placement of the fire control group, match barrel, improved sights, better ergonomics, lighter weight and increased magazine capacity.
It then became the full-size offering of the Thunder model range.[1]
The Thunder 9 is also sold under the name Firestorm or FS 9.
The Compact versions of the Bersa Thunder full-size handguns were introduced at the end of the 1990s. Initially the name was "Mini Thunder" later changed to "Thunder Ultra Compact".

Perspective
The Thunder 9 shares little in common with the other handguns in the company's product line.
Calibers
While the smaller Thunders are blow-back pistols similar to the Walther PPK, the other Thunder pistols are full-size, short-recoil handguns to handle the greater pressure of other cartridges.
The number after the name "Thunder" identify the cartridge fired. Thus, they are called the Thunder 9, Thunder 40, and Thunder 45 for the 9mm Luger, .40 S&W, and .45 ACP cartridges, respectively.
Design
The gun bears some resemblance to the Walther P88 pistol.
The slide and barrel are high strength steel and the frame is aluminum alloy. Available finishes are black matte, nickel, and a two-tone with a nickel finished slide and satin black frame. All the available finishing styles are non-reflective.
The polymer grips are integrated "wraparound" style. The trigger is double-action for the first shot, single-action thereafter.
The magazine is double stack and the slide remains open after the last round is fired. The magazine release button can be reversed for left-handed shooters and it has a "round in the chamber" indicator.
Operation
The pistol features ambidextrous safety, a decocker activated by the safety lever, emphasized sights, combat trigger guard, an integrated accessory mounting groove in the frame (added after the year 2000, in the Pro, for Professional, version), firing pin block.
The pistol will not fire unless the trigger is squeezed all the way back protecting from accidental falling.
The Thunder Ultra Compact features an individual security key to activate a security locking system located on the left side of the frame under the take down lever, in the locked position the hammer cannot be cocked, the trigger won't work in double action, the slide won't cycle and the gun cannot be disassembled.
The Thunder 9 is one of the easiest, if not the easiest, semi-automatic handgun to field strip for cleaning.
