Smith & Wesson SW

Common card · No. 446102

The Smith & Wesson SW series, most commonly referred to as the Smith & Wesson Sigma, was Smith & Wesson's first venture into using synthetic materials in pistol construction, with high-strength polymer material for the frame. The Smith & Wesson Sigma is somewhat infamous in the gun community due to its controversial history. The design of the original Sigmas were so similar to a Glock both in their design and operation that Smith & Wesson was sued by Glock over patent infringement. This resulted in Smith & Wesson having to make alterations to the design and pay an undisclosed settlement to Glock. The Sigma line was replaced by the similar but substantially improved Smith & Wesson SD series in 2010.
