The Model 4006 is part of Smith & Wesson’s Third-Generation metal-frame series and was an early, purpose-built .40 S&W design introduced in 1990. This configuration reflects that lineage with a full-size stainless-steel frame and slide finished in matte stainless, offering a durable build tailored for duty use of its era.
It operates on a short-recoil, locked-breech system and uses a DA/SA trigger with an ambidextrous, slide-mounted safety/decocker and an external spur hammer. The double-column magazine provides an 11+1 capacity, and the external extractor supports reliable cycling with the .40 S&W cartridge.
Sighting is straightforward with fixed 3-dot sights: a white-dot front blade paired to a 2-dot rear sight secured with a top set-screw. Rear slide serrations aid manipulation. The one-piece wraparound black synthetic grip features molded Smith & Wesson logos and checkering for a secure hold.
Details include a 4-inch barrel, a dustcover without an accessory rail, and clear factory markings: the frame is marked "MOD 4006" and the barrel hood is marked ".40 S&W." The included steel double-stack magazines are compatible with the Model 4006, rounding out a ready-to-use package.
