The Thunder UC Pro is a smaller, compact version of the Thunder Pro with all of the same functional features.
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 developed as a joint venture between Winchester and Smith & Wesson. It was an effort to to create a cartridge with the same power as the 10mm Norma round that the FBI had just started using, but in a shorter case. The shorter cartridge would facilitate accuracy and allow use of a smaller, more comfortable grip frame. The .40 S&W has become the cartridge of choice for many law enforcement agencies in the United States.
