If you’re considering adding a firearm to your arsenal, especially for concealed carry, the information provided will assist you in making an informed decision about this iconic airweight revolver.
A Closer Look at the Structure and Features
The heart of any firearm lies in its specifications, and the Smith & Wesson 637 is no exception. The 637 is crafted by Smith & Wesson, a name synonymous with quality and reliability in the firearms industry. Classified as a revolver, it operates on a double-action/single-action (DA/SA) mechanism, providing users with versatility in how they choose to operate the trigger. The caliber is chambered for the ubiquitous .38 Special, including +P rated ammunition, providing ample stopping power in a concealed carry package.
The revolver holds five rounds, a common capacity for snub-nosed revolvers designed for personal defense. This capacity, though modest, is balanced by the gun’s reliability and ease of use. The frame, a critical component determining weight and durability, is constructed from an aluminum alloy. This choice of material significantly reduces the overall weight of the firearm, which contributes to its suitability for concealed carry. The cylinder, where the cartridges reside, is made from stainless steel, adding resilience to the 637’s design, resisting wear and tear from the stresses of firing and handling.
The exterior finish, often a silver or matte appearance, is chosen for its aesthetic appeal and its ability to protect the gun’s components from environmental elements. The grips, whether factory-installed or aftermarket, are an essential element influencing the handling of the firearm. The standard grips are designed for comfortable and secure handling, but owners can customize them for a personalized experience. The light overall weight of the firearm, is one of the most appealing factors of this design. The barrel length, a crucial factor impacting accuracy, varies, typically ranging to just under two inches.
Dissecting the Details of Its Construction
Delving deeper, let’s examine the individual elements that come together to make the Smith & Wesson 637 such a popular choice. The aluminum alloy frame, the backbone of the pistol, gives the 637 its lightweight characteristic. This is a paramount advantage for concealed carry, making it comfortable to wear for extended periods. The lightweight nature, however, has an effect on the recoil, which can be more noticeable, as discussed later.
The stainless steel cylinder is made to withstand the pressures generated by the .38 Special cartridges. It is built to last, adding to the overall durability of the revolver. It also has a high resistance to the corrosive effects of the powder and primer residue produced by the fired rounds.
The barrel’s length is of considerable importance. A shorter barrel, while ideal for concealability, typically sacrifices some accuracy compared to longer-barreled firearms. The Smith & Wesson 637’s barrel length strikes a practical balance, allowing for ease of concealment while still providing enough accuracy for effective self-defense at typical engagement distances.
The DA/SA trigger system provides users with two operational choices. In double-action mode, pulling the trigger both cocks and releases the hammer, offering a longer, heavier trigger pull. In single-action mode, the hammer is manually cocked, resulting in a lighter, crisper trigger pull for increased accuracy. The user, therefore, has the flexibility to choose the mode of operation which suits their personal preferences. The trigger reset, the distance the trigger travels forward after firing, is important, allowing for rapid follow-up shots.
The sights of the S&W 637 typically include a front blade and a fixed rear sight. These provide a rudimentary sight picture, adequate for close-range defensive encounters. While not as precise as adjustable sights, they are simple, reliable, and well-suited to the revolver’s intended purpose.
The factory grips are designed to offer a secure and comfortable grip, which is crucial, especially given the revolver’s lightweight frame and the resulting recoil. Many aftermarket grip options are available, allowing owners to customize the firearm to their hand size and personal preferences. Some grip options may add comfort, while others can help to mitigate felt recoil.
The Smith & Wesson 637 incorporates internal safety mechanisms, providing additional protection against accidental discharge. These safety features are designed to be reliable and unobtrusive, allowing the firearm to be carried and used with confidence.
Assessing the Mechanics and Handling
The performance characteristics of the Smith & Wesson 637 are key to understanding its real-world capabilities. Accuracy, a primary concern for any firearm, is dependent on several factors, including the shooter’s skill, the ammunition used, and the firearm’s inherent design. When test-firing, the 637 typically produces groups of moderate size, more than adequate for self-defense.
The effect of barrel length is relevant here, as it can be a challenge to maintain a high degree of accuracy at extended ranges. The sight picture, though simple, is sufficient for quick target acquisition at close-quarters distances.
The lightweight frame of the 637 means that the recoil generated by the .38 Special cartridges, and especially +P rounds, is noticeable. Recoil management is crucial for accurate and rapid follow-up shots. The shooter has a greater felt recoil, making it important to focus on proper grip and stance.
Concealability is one of the most compelling aspects of this firearm. Its small size and lightweight construction make it ideal for various concealed carry methods. Whether using an inside-the-waistband (IWB) holster, a pocket holster, or another carrying option, the 637 easily disappears under clothing. The ease of concealment is a major reason why this gun is so popular.
Furthermore, the 637 excels in ease of use. Loading and unloading the cylinder is a straightforward process. The revolver’s design is known for its reliability. While mechanical issues are rare, the straightforward, simple design promotes a reliable function in a defense situation.
Weighing the Pluses and Minuses
To provide a balanced evaluation, let’s explore the pros and cons associated with the Smith & Wesson 637.
The strengths of the 637 are many. First, it is lightweight and easy to carry, making it suitable for everyday concealed carry. Its simple and reliable design makes it easy to maintain and operate. It provides effective stopping power, appropriate for self-defense situations. The 637 is also relatively affordable, making it accessible to a wide range of potential owners. Its ability to use .38 Special +P ammunition is another advantage, providing an increase in performance over standard .38 Special rounds. The firearm is well-suited to beginner shooters, offering an uncomplicated, reliable option for those new to firearms.
However, there are some disadvantages as well. The recoil, especially with +P ammunition, is significant, which can affect the shooter’s ability to maintain accuracy and control. The limited capacity of five rounds, while typical for this type of revolver, is a drawback compared to semi-automatic pistols that typically hold more rounds. The trigger can be heavy, especially in double-action mode, requiring deliberate and consistent pulls for accurate shooting. The simple sights may not be as ideal for precision shooting as more advanced sight systems. It is not the most ideal choice for extended range sessions due to its recoil and potentially heavier trigger.
Comparable Options and the Wider Landscape
Several other revolvers compete with the Smith & Wesson 637 in the concealed carry market. Competitors such as the Ruger LCR and the Smith & Wesson 642 offer similar features and functionalities. The Ruger LCR is known for its innovative polymer frame and lighter weight. The S&W 642, the 637’s hammerless sibling, is very similar, and popular for its snag-free design.
Comparing the 637 to these alternatives involves evaluating factors like price, weight, trigger feel, and overall ergonomics. Ultimately, the best choice will depend on an individual’s personal preferences and priorities. The S&W 637 stands out in its blend of affordability, reliability, and the well-established Smith & Wesson reputation.
