The S&W Model 4006 is a semi-automatic handgun introduced by Smith & Wesson on January 17, 1990 along with the new .40 S&W cartridge. It is a 3rd-generation S&W pistol.


This one served with the California Highway Patrol.
Here is an S&W 4006 with a picatinny rail and bobbed hammer. This model previously served with the California Highway Patrol.

The S&W 4006 features a stainless steel frame and slide, double action/single action handgun with 4-inch barrel, slide-mounted de-cock/safety and an 11-round staggered-column magazine. It was one of the new 3rd-generation S&W semi-autos, designed with input from famed gunsmith Wayne Novak of Parkersburg, WV. The 4006 introduced the new .40 S&W cartridge and featured a wraparound one-piece grip made of Xenoy versus the earlier standard 2-piece grip panels, as well as low-profile 3-dot Novak sights.[citation needed]

A lightweight aluminum alloy–framed S&W 4003/4043 was produced that weighed 800 grams (29 ounces) and was more comfortable to carry. The 4046 model was a DAO (double-action-only) pistol in all stainless steel. The first 2 digits in the model number indicate caliber. The last digit, either a 3 or 6, indicates aluminum or stainless steel frame, respectively. Various safety features include a safety lever (which blocks the firing pin from the hammer) as well as a magazine safety (which keeps the pistol from firing when no magazine is inserted). While a true double-action pistol, the firearm shares this magazine disconnect feature with Browning Hi-Power pistols: it cannot be fired without the magazine in place. This feature was developed to meet the needs of various law enforcement agencies interested in providing another level of safety for their officers.[1]
