Unveiling the Core: Specifications and Key Features
Model Variations
The Smith & Wesson 640, a member of the esteemed J-frame family, is known for its diminutive size and robust build. Its compact form factor makes it a prime contender for concealed carry, and its chambering in both .38 Special and .357 Magnum adds a layer of versatility. The models available will affect some of the specifications, but the core components remain the same.
General Specs
Built around a foundation of strength, the 640 boasts a frame constructed primarily from stainless steel. This choice of material contributes to its durability, its resistance to the elements, and, of course, its weight. This weight, though adding a touch to the overall package, is a welcome feature, helping to mitigate felt recoil, especially when firing the potent .357 Magnum rounds. The matte finish often found on these firearms helps to minimize glare and adds to the stealth factor, crucial for a concealed carry weapon.
The cylinder is the heart of the 640’s operation, typically holding five rounds. This five-shot capacity is a common feature in J-frame revolvers and represents a balance between stopping power and concealability. The cylinder is meticulously crafted, designed to withstand the pressures generated by high-performance ammunition. Its smooth rotation and precise alignment are key to the revolver’s consistent and reliable performance.
A short barrel is the hallmark of the 640. This feature enhances its concealability, making it easier to carry discreetly. The barrel length impacts the ballistic performance of the rounds, with shorter barrels slightly reducing muzzle velocity compared to longer barrels. However, the trade-off of a slight reduction in ballistics is often deemed acceptable for the enhanced portability that the short barrel provides.
The grips play a crucial role in how the gun feels in your hand and how controllable it is during firing. Smith & Wesson often equips the 640 with rubber grips, offering a secure and comfortable hold. The textured surface of these grips aids in maintaining a firm grip, even under stress or in adverse conditions. The grip design contributes significantly to the overall ergonomics, ensuring that the gun sits comfortably and allows for instinctive pointing. Other models may have wood grips, which offer aesthetics as well as a secure grip.
The sights, or lack thereof, are another defining feature. The 640 typically features fixed sights. These are simple and robust, unlikely to snag on clothing during the draw. The sights are designed for quick target acquisition, a critical factor in self-defense scenarios. Some models feature a tritium front sight for enhanced visibility in low-light conditions.
The trigger is a key aspect of the shooting experience. The 640 is typically a double-action-only (DAO) revolver. This means that each shot requires a long, deliberate pull of the trigger to both cock and release the hammer. While this system increases the safety of the firearm, it can also be a challenge for inexperienced shooters. The trigger pull is generally heavier than that of a single-action firearm. The weight of the pull is by design.
The Firing Line: Performance and Real-World Handling
Shooting Experience
Stepping onto the range with the Smith & Wesson 640 is a unique experience. The compact size and the potential for high-powered ammunition combine to create a firearm that demands respect.
The recoil, particularly with .357 Magnum loads, is noticeable. The lightweight frame and the powerful cartridge combine to deliver a sharp impulse. It is important to mention that this recoil is manageable with proper training and grip. The experience is less intense when using .38 Special or .38 Special +P ammunition. Many shooters prefer the .38 Special +P for everyday carry, balancing stopping power with reduced recoil. The shooter should use the ammunition type that they are most familiar with and can control.
Accuracy is a relative term when it comes to a compact revolver. At typical self-defense ranges (e.g., out to ten or fifteen yards), the 640 is more than capable of delivering effective shot placement. The fixed sights promote instinctive aiming, and the relatively heavy trigger pull encourages deliberate shots. Consistent groupings are achievable with practice, making it a reliable performer in the hands of a skilled shooter.
Reliability
One of the key factors to discuss is reliability. The Smith & Wesson 640 has earned a reputation for dependability. Its simple, robust design minimizes the potential for malfunctions. The absence of complex mechanisms reduces the points of failure. With proper care and maintenance, the 640 is an extremely dependable firearm that can be counted on when it matters most.
Handling and Ergonomics
The handling and ergonomics of the 640 are where its size comes into play. It’s a master of concealment. It disappears easily beneath clothing, making it ideal for everyday carry. Whether in an inside-the-waistband (IWB) holster, a pocket holster, or other carry method, the 640 readily adapts to different carry styles.
Ease of use is a mixed bag. Loading and unloading the revolver is straightforward, and the lack of external safeties simplifies operation. The double-action-only trigger, while contributing to safety, can present a learning curve for some shooters. The compact grips, while offering concealment, may require some adjustment for shooters with larger hands.
The grip design significantly affects the shooter’s control. The rubber grips provide a firm hold, allowing the shooter to maintain control during rapid fire or under stress. The grip shape facilitates natural pointing, allowing the shooter to quickly acquire a sight picture and deliver accurate shots.
Weighing the Scales: Pros and Cons of the Smith & Wesson 640
Pros
Some of the strong suits for the 640 start with its compact size and unparalleled concealability. This advantage allows for discreet carry in a wide range of situations. The revolver’s reliability and durability are legendary. Its simple design minimizes potential problems, contributing to its reputation for unfailing performance. The ease of use, once the trigger pull is mastered, adds to its practicality as a self-defense weapon. The versatility to chamber both .38 Special and .357 Magnum ammunition increases its appeal, providing a choice of power levels. The build quality of Smith & Wesson is well regarded.
Cons
The potential downsides begin with recoil, especially when firing .357 Magnum rounds. The compact size and lightweight frame contribute to a noticeable recoil impulse, which can be challenging for some shooters. The limited capacity of the five-round cylinder, while typical for J-frame revolvers, is a factor to consider. The heavy double-action-only trigger pull can be a challenge for accurate shooting until a shooter is familiar with it. The price point, while reasonable for the quality, may be a consideration compared to other, potentially more feature-rich options. The sights, while functional, are small.
Comparing Choices: The 640 in the Competitive Landscape
The Smith & Wesson 640 exists in a competitive market. To better understand where it fits, we can compare it to other popular models.
Smith & Wesson 442/642
The Smith & Wesson 442 and 642, also J-frame revolvers, share a similar size and capacity but often feature an aluminum alloy frame, making them even lighter. They are a good choice to consider because of their simplicity.
Ruger LCR
The Ruger LCR (Lightweight Compact Revolver) is another strong contender in the concealed carry market. It typically features a polymer frame, contributing to a light weight, and a more user-friendly trigger pull compared to some J-frame models. The LCR, with its unique design, also represents a strong competitor.
When choosing between these options, several factors come into play. If size and weight are the absolute primary concerns, the 442/642 might be the preferred option. If a lighter trigger pull and a different aesthetic are priorities, the Ruger LCR is worth considering. The Smith & Wesson 640, with its stainless-steel frame, offers a blend of durability, power, and concealability that continues to make it a popular choice.
