The Model 4566 pairs an all-stainless steel frame and slide with a brushed satin finish for a cohesive, durable build. Its 4.25-inch stainless barrel and full-size dimensions deliver the classic 4566 profile in .45 ACP with an 8+1 capacity via a single-stack magazine.
Controls are set up for service-ready handling: a DA/SA trigger system, an ambidextrous slide-mounted safety/decocker, and a left-side magazine release. The exposed spur hammer, external extractor, and a lowered/relieved ejection port round out the slide features.
Ergonomics include a rounded trigger guard with a serrated front face, vertical frontstrap serrations, and a one-piece wraparound textured synthetic grip with S&W medallion. This configuration provides a secure hold while maintaining the slim, single-stack profile.
Sighting is straightforward and durable with fixed, low-mount 3-dot sights: a fixed front sight with white dot and a rear with two white dots. Markings include the S&W circular crest and "Made in U.S.A." designation, underscoring its American manufacture and Third-Generation lineage.
