Smith & Wesson Model 5906

The Smith & Wesson 5906 is a pistol manufactured starting in 1988 by Smith & Wesson.

Design
The 5906 is a full-sized, double/single-action (DA/SA), staggered-column magazine, 9×19mm pistol. Its construction is all stainless steel. The 5906 is equipped with a magazine disconnect feature which is designed to deactivate the trigger if the magazine is not fully inserted. The pistol comes standard with either a 10- or 15-round magazine. Other features include ambidextrous safety levers, a one-piece rear wraparound grip, and a choice of either fixed sights or a rear sight fully adjustable for windage and elevation. Once a very popular model with law enforcement and military units in the United States, the DA/SA 5906 has been superseded by polymer-framed striker-fired models from Glock, Heckler & Koch, SIG Sauer as well as Smith & Wesson's own M&P line of polymer framed handguns in both 9mm and .40 calibers.

Variants
The first generation Smith & Wesson semi-auto pistol designations consist of two digits, such as Smith & Wesson Model 39 and Model 59. Second generation pistols are designated by three digits; these include the Model 459, Model 659, etc. Many second generation designs were eventually upgraded with various improvements, thus becoming the third generation pistols; these are identified by the addition of a fourth digit to the second generation model number: 5903, 5904, 5905, 5906, etc. However, there are exceptions to this numbering scheme, namely the third generation Value Series pistols such as the S&W Models 915 and 910, and the Model 457.
