What’s Included
- Smith & Wesson Model 4506-1 pistol

The 4506-1 is part of Smith & Wesson’s third-generation 4500 series, a full-size .45 ACP platform built with a stainless-steel frame and slide in a satin stainless finish. Its 5-inch stainless barrel and single-stack magazine well deliver the classic 8+1 .45 ACP configuration in a durable service-pistol format.
This model uses a DA/SA action with an ambidextrous slide-mounted safety/decocker that includes a red fire dot. Internal safeties include a firing-pin block and a magazine disconnect. An external extractor and lowered ejection port support reliable extraction and ejection.
Sights are an adjustable rear paired with a ramped front sight featuring a white dot, providing a clean sight picture. The pistol retains its factory one-piece wraparound black synthetic grips with S&W medallions for a secure, consistent hold.
The -1 revision’s rounded trigger guard, smooth curved trigger, and spur hammer are characteristic features of this variant. As a member of S&W’s third-generation service-pistol line, the 4506 series saw wide professional adoption in the 1990s, with this configuration aligning to the robust, duty-oriented features that made the model notable.
Included are two steel 8-round magazines with numbered witness holes, complementing the pistol’s standard 8+1 capacity.
