A Classic Design, Built to Last
From the moment you handle the S&W 637, you’re aware of its simplicity and elegance. This is a revolver that prioritizes function over flashy aesthetics, built on a foundation of proven design. The frame, often constructed from durable aluminum alloy, is lightweight, making it comfortable to carry all day long. This material choice contributes significantly to the 637’s appeal as an easily concealable firearm. The cylinder, on the other hand, is typically crafted from stainless steel, offering the necessary strength to withstand the pressures of repeated firing and provide resistance to corrosion.
The finish of the 637 can vary depending on the specific model, but often it features a matte silver or a more subdued, matte black appearance. This finish not only provides a practical aesthetic but also helps to minimize glare, an important consideration in defensive situations. The overall design reflects Smith & Wesson’s long-standing commitment to producing reliable, high-quality firearms. It’s a design that has stood the test of time, proving its worth in the hands of countless users. The compact nature of the S&W 637 is its most striking feature. The overall length, height, and width are kept to a minimum, allowing for easy concealment in a variety of carry methods.
The S&W 637’s construction speaks to its intended purpose: to be a reliable and easily carried personal defense firearm. The simplicity of the design also contributes to its ease of maintenance.
Examining Key Features
The heart of the S&W 637, like all revolvers, is its cylinder. The S&W 637 is typically chambered in .38 Special +P, a popular and effective cartridge for self-defense. This chambering allows for a balance of power and manageable recoil, especially in a lightweight frame. The cylinder typically holds five rounds, a standard capacity for J-frame revolvers. While it may seem modest compared to modern semi-automatic pistols, the simplicity and reliability of a revolver often outweigh the perceived disadvantage of fewer rounds, particularly in a self-defense scenario where close-quarters encounters are more common.
The action of the S&W 637 is another key element. It is typically a double-action/single-action (DA/SA) revolver. This means the trigger can be pulled all the way through, cocking and then releasing the hammer (double-action), or the hammer can be manually cocked for a lighter, shorter trigger pull (single-action). Many owners favor the double-action method for its ease of use and added safety, particularly under stress. The single-action mode is sometimes employed for more precise shots, but its use is less common in self-defense scenarios. The barrel length on the 637 is typically short, often just under two inches. This short barrel further enhances its concealability, making it easy to carry in a pocket, inside the waistband (IWB), or in other concealed carry holsters.
The sights on the S&W 637 are typically simple, often consisting of a fixed front sight and a shallow notch at the rear. This simplicity is in keeping with the revolver’s intended purpose – to be a point-and-shoot firearm for close-quarters defense. While some shooters might prefer more elaborate sights, the fixed configuration provides a quick and clear sight picture at typical self-defense ranges.
The grips play a crucial role in handling the recoil and comfort of the firearm. The original factory grips are often made of rubber or a polymer composite, designed to provide a secure and comfortable grip, even with wet hands. These grips also absorb some of the recoil, making the shooting experience more manageable, especially with the snappy recoil of +P ammunition.
Finally, safety is always a primary concern with any firearm. The S&W 637 incorporates internal safety features, such as a firing pin block, which prevents the firing pin from striking the primer unless the trigger is fully pulled. This safety mechanism helps prevent accidental discharges, adding an extra layer of security for the user.
Putting It to the Test: Performance in Action
Shooting the S&W 637 is an experience that demands respect. The short barrel and lightweight frame mean that recoil, especially with .38 Special +P loads, is noticeable. Understanding this is crucial for effective handling. The trigger pull in double-action mode is typically heavy, requiring a deliberate and consistent pull to fire the round. This can be challenging for some shooters, especially when rapid firing is needed. The single-action trigger pull, when the hammer is manually cocked, is significantly lighter and smoother, which can improve accuracy, but requires the user to be comfortable and familiar with the process of cocking the hammer.
Accuracy with the S&W 637 is adequate for its intended purpose. At self-defense ranges, typically out to 7 to 15 yards, most shooters can achieve decent groupings. The fixed sights necessitate a consistent sight picture and practice to master. The short barrel, while contributing to concealability, can make long-range accuracy more challenging. The trade-off is in portability and ease of carry. The recoil of the S&W 637, as mentioned earlier, is significant. With +P loads, the gun can be a handful. Proper grip technique is crucial for managing recoil and maintaining control. Consistent practice is essential to develop the necessary skills to effectively handle this firearm. The recoil can be a deterrent for some shooters, but many find that with consistent practice, it becomes manageable. Reliability is a hallmark of the S&W 637. Revolvers, by their nature, are mechanically simple and less prone to malfunctions than semi-automatic pistols. The 637 is known for its dependable performance.
When considering handling and ergonomics, the size and weight of the S&W 637 are its strongest assets. It disappears easily when carried. The rounded profile of the gun, when properly holstered, is less likely to print through clothing. The grips, as mentioned, are usually designed to provide a comfortable and secure hold, but may require some adaptation for shooters with larger hands. Reloading a revolver is inherently slower than reloading a semi-automatic pistol. Speed loaders or speed strips can help speed up the process. It takes practice to master smooth and efficient reloading.
