Our Assessment: This Smith & Wesson 4006TSW represents the duty grade evolution of the Third Generation S&W autos, built during the height of American law enforcement’s transition to the .40 S&W cartridge. Issued to the California Highway Patrol and marked with a distinctive CHP serial prefix, this pistol reflects the agency’s emphasis on durability, controllability, and officer safety. The Tactical Smith & Wesson configuration incorporates Novak sights, a decocker only system, and a bobbed hammer, all features intended to reduce snag risk and streamline defensive handling under stress.

The .40 S&W cartridge was developed in the early 1990s to balance terminal performance with manageable recoil, quickly becoming a dominant law enforcement chambering. This example retains a bright bore with sharp rifling and clear markings, while exterior wear is consistent with professional service use rather than abuse. As a whole, it stands as an authentic California Highway Patrol sidearm that captures a distinct period in modern American policing and Smith & Wesson’s law enforcement legacy.
