The Smith & Wesson Model 645 holds a significant place in the history of semi-automatic pistols. This article delves into the details of this iconic firearm, exploring its design, history, performance, and lasting legacy. Whether you're a seasoned firearms enthusiast or a curious newcomer, this comprehensive guide will provide valuable insights into the Model 645.
A Look Back at the Model 645's History
Introduced in 1981, the Smith & Wesson Model 645 was a response to the growing demand for a reliable and accurate semi-automatic pistol chambered in .45 ACP. At the time, many law enforcement agencies and civilians sought a higher-capacity alternative to the venerable 1911, and the 645 aimed to fill that niche. Its design incorporated several innovative features for its era, solidifying its position as a serious contender in the market.
Design and Features: Examining the Model 645
The Model 645 stands out for its robust build quality and innovative features:
- Caliber: .45 ACP (Automatic Colt Pistol) – a powerful and widely-used cartridge known for its stopping power.
- Capacity: Typically 7+1 rounds – offering a substantial increase in capacity compared to standard 1911s.
- Construction: Constructed primarily from steel, providing durability and reliability even under harsh conditions. The steel frame contributes significantly to the pistol's weight.
- Double-Action/Single-Action (DA/SA) Trigger: The Model 645's DA/SA trigger system offers flexibility. The first shot is fired in double-action mode, requiring a longer, heavier pull. Subsequent shots are fired in single-action mode, with a significantly lighter trigger pull.
- Safety Features: The pistol features a manual thumb safety, providing an additional layer of security.
Strengths of the Design:
- Reliability: Known for its robust construction and dependable function, even under challenging circumstances.
- Accuracy: The Model 645's design generally leads to good accuracy at typical self-defense and target ranges.
- Power: The .45 ACP cartridge delivers significant stopping power.
Potential Drawbacks:
- Weight: The all-steel construction makes the pistol heavier than some polymer-framed alternatives. This can affect concealability and prolonged carry comfort.
- Recoil: The powerful .45 ACP cartridge produces noticeable recoil, which can be a factor for some shooters. Mastering recoil management is crucial for consistent accuracy.
- DA/SA Trigger: While offering flexibility, the longer DA trigger pull can be less desirable for some users compared to striker-fired pistols.
The Model 645's Legacy and Current Market Position
While production of the original Model 645 has ceased, its influence on subsequent Smith & Wesson designs and the broader handgun market is undeniable. Its impact can be seen in the features and designs of later models. While not as readily available as some newer handguns, the Model 645 remains a sought-after collectible and a testament to S&W's engineering prowess.
Conclusion: A Classic Worth Considering
The Smith & Wesson Model 645 represents a significant chapter in the history of semi-automatic pistols. Its blend of power, reliability, and robust construction solidified its reputation as a capable and dependable firearm.
