What is s&w sigma?

The Smith & Wesson Sigma series is a line of polymer-framed, striker-fired semi-automatic pistols that were introduced in the early 1990s. The Sigma pistols were designed as a more affordable alternative to Smith & Wesson's popular M&P line of handguns.

The Sigma pistols are known for their ergonomic design, lightweight construction, and reliability. They are available in various calibers, including 9mm, .40 S&W, and .45 ACP. The pistols feature a Picatinny rail for attaching accessories such as lights or lasers, as well as interchangeable grip panels for a customizable fit.

Despite their affordability and popularity, the Sigma pistols have received some criticism for their heavy trigger pull and lackluster accuracy compared to other handguns in their class. However, they remain a popular choice for shooters looking for a budget-friendly option for self-defense or recreational shooting.
