The Legacy of the J-Frame
Evolution of Compact Revolvers
Smith & Wesson, a name synonymous with American firearm heritage, boasts a long and storied history of producing quality handguns. From law enforcement to civilian self-defense, Smith & Wesson’s reputation for reliability and craftsmanship is well-established. Within their extensive lineup, the Model 640-2 stands out as a particularly popular choice for those seeking a compact and potent concealed carry option. This article aims to delve deep into the features, examine the pros and cons, and offer a comprehensive look at the Smith & Wesson 640-2, helping you determine if this revolver is the right handgun to meet your personal protection needs.
Significance of the 640 Series
Before exploring the 640-2 specifically, it’s essential to understand the lineage from which it sprung. The Smith & Wesson J-frame revolvers have a long history, evolving into a class of compact revolvers that have served as reliable sidearms for generations. These small-frame revolvers, known for their concealability, have been carried by law enforcement officers and civilians alike. The J-frame’s design prioritizes ease of carry and ease of concealment, a pivotal characteristic of any self-defense firearm.
The -2 Designation
The 640 represents a refinement of the J-frame concept, introducing a stainless-steel frame for enhanced durability and corrosion resistance. This innovation provided a more resilient handgun than earlier models, especially in environments prone to moisture or harsh conditions. The -2 designation signifies a particular iteration within the 640 lineage, often indicating subtle refinements and improvements over the original design. The model number itself gives us clues to its purpose; the “6” signifies a stainless-steel frame, and the “40” denotes the use of a small-frame design.
Unveiling the Design and Features
Frame and Build
The Smith & Wesson 640-2 is more than just a firearm; it is a testament to practical design.
Constructed entirely from stainless steel, the frame of the 640-2 provides a robust foundation for the handgun. This stainless steel construction offers significant advantages. It provides enhanced resistance to the elements, making it a reliable choice in various conditions. The all-stainless-steel build ensures the firearm can endure a significant degree of wear and tear, and stainless steel makes cleaning easier, a critical factor for those prioritizing daily carry. The overall size and weight of the 640-2 contribute significantly to its appeal. Its compact dimensions make it exceptionally easy to conceal. This pocket-sized revolver slips easily into a variety of holsters, making it an ideal option for those seeking an unobtrusive self-defense solution.
Chambering and Capacity
The 640-2 is typically chambered in the powerful .357 Magnum cartridge. The option of firing .38 Special ammunition further increases its versatility. With a five-round capacity, the 640-2 delivers a balance between firepower and compactness. The .357 Magnum round is known for its impressive stopping power. This significant ballistic advantage, combined with the 640-2’s concealable form, makes for a potent defense combination.
Trigger Mechanism
The trigger mechanism is a crucial element of this revolver’s design. The 640-2 operates with a double-action-only (DAO) trigger. This means the shooter must pull the trigger all the way through to both cock and release the hammer. The DAO system enhances safety by eliminating the need for a manual safety and provides a smooth, consistent trigger pull. This consistent trigger pull is useful for achieving reliable, predictable shots. While the trigger pull can be on the heavier side, a double-action trigger makes for a safer, yet effective, firing mechanism.
Sights
The sights are minimalist, reflecting the gun’s intended use as a close-range defensive tool. You will typically find a fixed front sight blade and a notched rear sight, a streamlined system designed for quick target acquisition in close-quarters scenarios. The sight picture, though simple, is adequate for this purpose. While some may find these basic sights limiting for longer distances, their design emphasizes speed and ease of use in critical defensive situations.
Grips
The grips on the 640-2 are typically made of rubber. The rubber grips offer a secure and comfortable hold, mitigating some of the felt recoil, especially when firing .357 Magnum rounds. Another attractive option is that, because the J-Frame design has been around for a while, there’s a rich aftermarket support system. Custom grips are readily available. This allows you to personalize the feel and aesthetic of the firearm to meet your preferences.
Advantages: The Strengths of the 640-2
Concealability
The Smith & Wesson 640-2 offers a compelling set of advantages, making it a strong contender in the concealed carry market.
The defining characteristic of the 640-2 is its exceptional concealability. Its small size and relatively low weight make it suitable for a variety of carry methods. Pocket carry, inside-the-waistband (IWB), and ankle carry are all viable options. This flexibility ensures the 640-2 can be adapted to individual preferences and needs. The ability to remain concealed is a significant factor in the choice of a defensive handgun, and the 640-2 excels in this aspect.
Reliability
Smith & Wesson firearms, including the 640-2, are known for their reliability. Their designs utilize mechanical simplicity. The 640-2 is built with a robust construction, with few moving parts, which contributes to this reputation. The lack of complex mechanisms often translates to fewer points of failure. The DAO trigger, which removes the manual safety, also helps prevent malfunctions. With proper care and maintenance, this revolver is known to perform consistently.
Powerful Caliber
The .357 Magnum chambering grants the 640-2 significant stopping power. The .357 Magnum round is renowned for its high energy and effectiveness against threats. The ability to also use .38 Special ammunition provides versatility. This allows for the use of ammunition with less recoil for training or self-defense situations.
Durability
The stainless-steel construction also adds significantly to the 640-2’s durability. The gun can endure years of use and exposure to the elements. The corrosion resistance provided by the stainless steel ensures that the 640-2 remains functional in various environments. This longevity makes it a sound investment for those seeking a reliable self-defense tool.
Disadvantages: Considerations and Trade-Offs
Recoil
While the 640-2 is an excellent handgun, it is important to acknowledge its limitations.
The recoil of the .357 Magnum in a lightweight, compact frame can be substantial. This is especially true during rapid firing sequences. The firm grip required to manage recoil can affect the shooter’s ability to acquire follow-up shots quickly. While the use of .38 Special ammunition mitigates the recoil, the .357 Magnum rounds do demand proficiency and practice.
Trigger Pull
The double-action trigger, while adding to the safety of the 640-2, presents a challenge. A long and heavy trigger pull can make it difficult for some shooters to achieve accurate and consistent results, especially at longer distances. Regular practice is essential to mastering this trigger. Proper technique and trigger control become paramount in this respect.
Capacity
The five-round capacity, while typical for J-frame revolvers, is a potential drawback compared to semi-automatic pistols with higher capacities. In a self-defense situation, the limited number of shots requires more careful shot placement and efficient targeting.
Sighting System
The minimalist sighting system, while suitable for close-range defense, can pose a disadvantage at greater distances. Those accustomed to the more refined sights found on larger handguns may find the 640-2’s sights limiting.
Performance and Practical Application
Accuracy
Understanding the performance of the 640-2 is crucial.
Accuracy with the 640-2 is attainable with proper practice. The short barrel and DAO trigger require a focused approach to shooting. The emphasis on proper grip, stance, and trigger control is essential. It’s important to find ammunition that works well with your gun and shooting style.
Concealed Carry Applications
The 640-2 excels in a variety of concealed carry applications. Its compact dimensions make it suitable for pocket carry, inside-the-waistband (IWB) carry, and ankle carry. Comfort and accessibility should be considered when selecting a carry method. The choice of holster will influence the ease of access and the overall comfort during daily carry.
Ammunition Selection
Ammunition selection is critical for self-defense. It is best to carry a quality brand name ammunition. The .357 Magnum offers significant stopping power. The .38 Special ammunition provides a lower recoil option for practice or a more comfortable carry experience.
Comparisons and Considerations
Comparisons to Similar Handguns
Comparing the Smith & Wesson 640-2 to other handguns is helpful.
Other J-frame revolvers such as the S&W 642 and 442 offer similar characteristics but may lack the .357 Magnum capability. Semi-automatic pistols, such as the Glock 43/43x, offer a higher capacity, and easier trigger pulls. However, the 640-2 distinguishes itself with its robustness and the potent .357 Magnum chambering. The key to choosing the right firearm is to consider your individual needs, preferences, and skill level.
Ownership and Maintenance
Cleaning and Lubrication
Responsible ownership of the Smith & Wesson 640-2 involves proper maintenance.
Regular cleaning and lubrication are essential for maintaining the firearm’s functionality and longevity. Follow the manufacturer’s instructions for disassembly and cleaning. Use appropriate cleaning solvents and lubricants specifically designed for firearms. Store the 640-2 in a secure location, such as a gun safe, away from children and unauthorized individuals. Practice safe gun handling techniques and always be aware of the firearm’s condition.
Final Thoughts
The Smith & Wesson 640-2 is a compelling option for concealed carry, with its combination of power, reliability, and concealability. The strong build, and proven design make it a solid choice for self-defense. The .357 Magnum chambering and the ability to use .38 Special ammunition give this gun adaptability for the user. The inherent trade-offs of recoil, limited capacity, and the trigger mechanism should be considered. This revolver is a good choice for those who prioritize concealability and a powerful defensive weapon. The Smith & Wesson 640-2 will provide consistent service for many years, making it an excellent option for those seeking a dependable and compact self-defense solution.
