About the Handgun:
The Thunder 9 was the first gun made in the Thunder series of pistols from Bersa. It was introduced into the US market only after the lifting of the Clinton-era ban in 2004. Addressing both the requirements of the ban and surging consumer demand for a concealable carry pistol, the smaller Thunder 9 Ultra Compact was introduced in 2000. Patterned closely after the earlier, double-stack 9mm Model 90, the Thunder 9 features an aluminum alloy frame for lightness, with the rest of the pistol's metal parts made of 4140 steel.
About the Manufacturer:
This Argentina company was founded in the mid 1950s by three Italian immigrants, all who were mechanical engineers. At first they just made parts under contract for another now defunct Argentina arms manufacturer. In 1959 they began making their own pistols and in 1960 they established their trademark name - Bersa. Their pistols today are known worldwide for both their reliability and economy.
About the Cartridge:
This cartridge was introduced along with the Luger semi-automatic pistol. The pistol and cartridge was first adopted by the German Navy in 1904 and then by the German Army in 1908. This cartridge has since been adopted by the military of practically every non-Communist power. It has become the most popular and widely-used handgun cartridge in the world. Performance wise, the 9mm cartridge has somewhat more power than the .38 Special but falls well short of the .357 Magnum.
