The slide is marked "40 TACTICAL" with the S&W crest, and the frame is marked "MOD 4003TSW," clearly identifying this TSW-series variant. It is chambered in .40 S&W with a 4" barrel and an 11+1 capacity, configured as a full-size pistol made in the USA.
The pistol combines a matte stainless slide with an aluminum-alloy frame in an alloy-tone finish. Functional grip surfaces include a checkered frontstrap, a rounded trigger guard, and a one-piece black wrap-around checkered grip with the S&W medallion.
It operates in DA/SA with a slide-mounted safety/decocker and an external spur hammer. Vertical rear slide serrations aid manipulation while keeping the profile clean and consistent with the TSW line.
Sighting is straightforward with fixed 3-dot sights, featuring a dovetailed front and a dovetailed rear for secure, serviceable installation. A proprietary TSW equipment rail section is attached under the dust cover with two fasteners, providing an accessory mounting interface specific to this model.
