The Model 645 represents S&W's all-stainless Second Generation metal-frame design, combining brushed flats with matte rounds for a purposeful finish. It is a full-size pistol with a 5-inch barrel and an 8+1 capacity, chambered in .45 ACP. The front and back straps are checkered for added control, and the trigger guard has a squared, serrated front.
Controls are set up for confident operation, with a double-action/single-action trigger system and an ambidextrous slide-mounted safety/decocker featuring a red "fire" index dot. The magazine release is on the left side, and the pistol uses a spurred hammer. A mild magwell bevel assists magazine insertion.
Sighting is straightforward and adjustable. The front sight is a ramped blade with an orange insert for visibility, paired with a screw-adjustable square-notch rear sight. The slide includes rear cocking serrations and an internal spring-steel extractor for reliable case handling.
This example was manufactured in 1988 in the United States and carries model and caliber markings as expected. It is recognized as S&W's first commercial .45 ACP autoloader, placing it as a noteworthy piece within the brand's 1980s Second Generation lineup. Black checkered synthetic grip panels with S&W medallions complete the factory configuration.
