About the Handgun:
The Sigma series is Smith & Wesson's first endeavor into polymer framed pistols. This striker fired model, designed for simplicity and economy, was strikingly similar to the Glock. So much so, that law suits and cash settlements ensued between the companies, ultimately allowing Smith & Wesson to continue producing the Sigma series.
About the Manufacturer:
This company began in 1852 when Horace Smith and Daniel Wesson entered a gunmaking partnership in Norwich Connecticut. In 1857 they produced the first metallic cartridge breech-loading revolver. Their first double-action revolver was produced in 1880. In 1964 the company passed from Wesson family control, and subsequently several conglomerates took control of it. From 1987 to 2001 Tomkins PLC, a British company, owned Smith & Wesson. In March 2000 Smith & Wesson signed an agreement with the Clinton Administration in order to avoid lawsuits. This agreement was not at all liked by the gun owning public and boycotts and floods of used S&W firearms in the market nearly ruined the company. On May 11, 2001, Saf-T-Hammer Corporation acquired Smith & Wesson Corp. from Tomkins PLC for a fraction of what Tomkins originally paid. The new company, Smith and Wesson Holding Corporation, publicly renounced the Clinton agreement which was received positively by the firearms community.
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.
