The Smith & Wesson Model 645 holds a significant place in the history of semi-automatic pistols. This article will explore its design, features, history, and lasting impact on the firearm market. We'll delve into its strengths and weaknesses, examining why it remains a sought-after pistol for collectors and shooters alike. Understanding the Model 645 requires looking beyond its simple specifications; it's a story of innovation, evolution, and a legacy that continues to resonate.
The Model 645: Design and Features
The Smith & Wesson Model 645, introduced in 1983, was a significant departure from Smith & Wesson's traditional revolver-focused lineup. It was designed as a full-sized, double-action/single-action (DA/SA) semi-automatic pistol chambered in the popular .45 ACP caliber. This marked a conscious effort by Smith & Wesson to compete in the growing market for high-capacity, reliable semi-automatic handguns.
Several key features defined the Model 645:
-
.45 ACP Chambering: The choice of .45 ACP reflected the demand for a powerful and effective cartridge for self-defense and law enforcement applications.
-
Double-Action/Single-Action (DA/SA) Trigger: This offered versatility, allowing for both a fast, double-action shot and a more accurate single-action follow-up.
-
Steel Frame: A robust steel frame ensured durability and reliability, essential qualities for a service pistol.
-
Eight-Round Magazine Capacity: At the time, this was considered a significant capacity for a .45 ACP pistol, enhancing its tactical potential.
Internal Mechanics and Reliability
The Model 645 employed a short recoil-operated, locked-breech system. This system, while relatively complex compared to simpler blowback designs, ensured reliability and accuracy, even under duress. However, this complexity also meant the Model 645 had more intricate internal parts, potentially making it more susceptible to malfunctions if not properly maintained.
The gun's hammer-forged barrel contributed to its accuracy and longevity. This process, which involves shaping the barrel by repeatedly striking a steel blank, creates a more durable and precise barrel than other manufacturing methods.

History and Production
The Model 645 was produced by Smith & Wesson from 1983 to 1990. Its initial introduction met with considerable success, gaining popularity among law enforcement agencies and civilian shooters alike. However, its production was eventually discontinued, partly due to the rising popularity of polymer-framed pistols, which were lighter and often less expensive.
Market Competition and Decline
The late 1980s and early 1990s witnessed a significant shift in the handgun market. The introduction of lightweight, polymer-framed semi-automatic pistols, such as the Glock 17 and other similar designs, offered a lighter-weight and often more cost-effective alternative. The heavier steel-framed Model 645, while robust, struggled to keep up in a market increasingly focused on these lighter options. This contributed significantly to the decision to discontinue its production.
The Model 645 Today: Collectibility and Legacy
Despite no longer being in production, the Smith & Wesson Model 645 remains a desirable firearm for collectors and enthusiasts. Its robust construction, classic design, and historical significance contribute to its continued appeal. Finding a well-maintained Model 645 in today's market can be challenging, and prices often reflect its collectible status.
Comparison to Modern .45 ACP Pistols
Modern .45 ACP pistols offer several advantages over the Model 645, including lighter weight, higher magazine capacities, and advanced features like accessory rails and improved ergonomics. However, the Model 645's inherent reliability and robust construction remain appealing to some shooters. The choice between a modern .45 ACP and a Model 645 ultimately depends on individual preferences and priorities.
Conclusion
The Smith & Wesson Model 645 represents a pivotal moment in Smith & Wesson's history and the evolution of semi-automatic pistols. While its production may have ended, its legacy persists. For those interested in firearms history or seeking a robust, classic .45 ACP, the Model 645 continues to hold a unique and captivating appeal. Understanding its history, design, and place in the firearm market provides valuable insight into the development of modern semi-automatic pistols.
