The 4566TSW 45 Tactical pairs an all-stainless slide and frame with a 4.25-inch stainless barrel for a durable, full-size .45 ACP platform. The matte stainless finish is consistent across the slide and frame, and the pistol retains the series-correct external hammer with a ring-style spur.
Controls are duty-oriented and include a DA/SA trigger system, an ambidextrous slide-mounted safety/decocker, a firing pin block, and a magazine disconnect safety. Fixed, low-mount dovetailed sights front and rear provide a snag-resistant sight picture.
This TSW variant incorporates a factory under-frame accessory rail block secured by two screws, along with practical frame features like front strap checkering and a rounded trigger guard. A one-piece wraparound textured black synthetic grip with S&W logo medallions offers a secure hold.
Capacity is 8+1 in .45 ACP. The slide is marked '45 TACTICAL' and the frame is marked 'MOD 4566TSW,' aligning with the Tactical Smith & Wesson series configuration. Made in the United States, this example includes five factory S&W magazines and two holsters to round out the package.
