About the Gun

The Thunder 40 was the first Bersa pistol chambered for .40 S&W. Due to the 1994 U.S. ban on magazines exceeding 10 rounds capacity, the full-size Bersa Thunder 40 with a magazine design capacity of 13 was initially unable to enter the U.S. market. Subsequently, Bersa introduced a compact version, the MiniThunder 40, in 2000 that met that ban restrictions. Since the ban has lifted both versions are now available.

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.
