The Smith & Wesson Sigma, was Smith & Wesson's first venture into using synthetic materials in pistol construction, using high-strength polymer material for the frame. The pistol is similar to a Glock safe-action pistol in both its design and operation, leading to controversy and speculation regarding the pistol's patents' legality.
Description
Created in 1994, the Sigma incorporates a pre-set striker firing mechanism. It is available in both .40 S&W cartridge and 9×19mm Parabellum, being one of the first pistols purpose-designed to handle the .40 S&W. Similarly styled sub-compact designs in .380 ACP and 9×19mm were also produced. A limited number of these pistols were also chambered in .357 SIG.[5] Material used for the slide is zinc-aluminium alloy known as ZAMAK.[6]
Patent issue
The Sigma series pistols were so similar to the competing Glock pistols that Glock sued Smith & Wesson for patent infringement. The case was settled out of court in 1997, with S&W agreeing to make alterations to the Sigma design and pay an undisclosed amount to Glock.[7]
