Smith & Wesson introduced the Model 4006 in 1990, and it earned a place in police service almost at once. It is an all-metal, stainless steel semi-automatic in .40 S&W, and the extra weight helps tame recoil from a round that can feel sharp in lighter pistols.

This one has a 4.1 inch barrel and an 11-round magazine, and weighs about 2.2 pounds by the listing. It is a hammer-fired pistol of the third generation, which many shooters rate for a smooth double-action first pull and a good single-action break. The stainless finish resists rust and wears gracefully.

The 4006 is an older design, so parts and magazines are not as common as they are for a Glock. Before you buy, make sure you are comfortable with the supply. Used magazines can be found, but they cost more than the polymer-frame kind.

For someone who enjoys classic police guns, it is a pleasant pistol to shoot. Study the photos for wear on the finish. It is sold used and as described. It ships to your FFL dealer, and the background check is completed there.
