A Legacy of Steel and Innovation
The world of firearms is filled with legendary names and innovative designs. Among these, Smith & Wesson stands as a titan, a manufacturer synonymous with quality, reliability, and a rich history. Their contributions to law enforcement, sport shooting, and personal defense are undeniable. Their stainless steel revolvers, in particular, have earned a reputation for their resilience and longevity, making them sought-after options for those who prioritize reliability. The 646 is a direct descendant of this proud heritage, representing Smith & Wesson’s dedication to producing firearms that can withstand the rigors of regular use.
Born from Demand: The .40 S&W Evolution
Before exploring the intricacies of the 646, we need to acknowledge the powerhouse cartridge it chambers: the .40 Smith & Wesson. This round emerged as a collaborative effort between Smith & Wesson and Winchester, a response to the FBI’s need for a cartridge with more stopping power than the 9mm Parabellum, but with less recoil than the 10mm Auto. The .40 S&W quickly gained popularity, bridging the gap between the two existing cartridges. The .40 S&W offers a compelling balance of power, manageable recoil, and magazine capacity, making it a favorite for both law enforcement and civilian self-defense.
Building the 646: Form and Functionality
The Smith & Wesson 646 is built upon the L-frame platform, a robust design that strikes a balance between manageable size and substantial strength. The frame and cylinder are crafted from stainless steel, a material that provides exceptional resistance to corrosion and wear. This construction allows the revolver to withstand harsh conditions, ensuring its continued functionality even after repeated use and exposure to the elements. The stainless steel finish also gives the 646 a sleek, professional appearance.
The standard barrel length is typically around five inches, a length that provides a good balance between accuracy and portability. This barrel length facilitates a longer sight radius, contributing to improved accuracy, particularly at longer ranges. The sights themselves are usually of the adjustable rear sight with a prominent front sight. This combination allows for precise aiming and easy target acquisition. The ergonomics of the grip are also vital, ensuring comfortable handling and effective recoil management.
Mechanism Marvel: How the 646 Works
The 646 operates with a double-action/single-action (DA/SA) mechanism. This means that the trigger can be pulled to both cock and fire the hammer (double-action), or the hammer can be manually cocked for a lighter, crisper trigger pull (single-action). The 646 offers flexibility in how you choose to fire the weapon. The trigger pull in double-action mode is typically longer and heavier, requiring a deliberate pull. In single-action mode, the trigger pull is significantly lighter and shorter, promoting greater precision.
One of the distinctive features of the 646 is the utilization of moon clips. Moon clips are small, circular pieces of metal designed to hold the ammunition in place, allowing for faster and easier loading and unloading. The moon clips of the 646 eliminate the need to individually load rounds into the cylinder. This feature significantly speeds up the reloading process, which is a great advantage in practical shooting situations.
The .40 S&W and the 646: A Powerful Combination
The .40 S&W cartridge’s capabilities are well-suited for the 646 platform. The .40 S&W offers impressive energy at the muzzle, translating to significant stopping power. The five-inch barrel further optimizes the cartridge’s performance. The .40 S&W’s ballistic characteristics make it a solid choice for self-defense. The 646’s construction, combined with the .40 S&W, makes this revolver a formidable defensive weapon.
Weighing the Advantages and Disadvantages
The Smith & Wesson 646 has numerous advantages. Its stainless-steel construction guarantees remarkable durability and resilience. The revolver’s accuracy, aided by the barrel length and adjustable sights, is a notable strength. The moon clips provide rapid reloading. Its rugged build means it handles the .40 S&W round with ease.
There are considerations, of course. The overall weight of the 646, due to its stainless-steel build, is heavier than some polymer-framed handguns. The cylinder capacity, at six rounds, is less than the capacity offered by some semi-automatic handguns. The cost, can be on the higher side, though the quality and durability are reflected in the price.
Shooting Experience: A Hands-On Perspective
Shooting the 646 is a rewarding experience. The recoil, though present, is manageable due to the revolver’s weight and the L-frame design. The balance of the gun contributes to good control during rapid firing. The trigger pull is typically crisp in single-action mode. The user has great control over the weapon during fire. With practice, the 646 can achieve impressive accuracy.
Maintenance and Long-Term Care
Maintaining the Smith & Wesson 646 is essential for preserving its performance and longevity. Regular cleaning and lubrication are paramount. Use a quality gun cleaning solvent and lubricating oil. Pay close attention to the cylinder, barrel, and action. Proper storage in a secure and dry environment will also protect the 646 from damage. Regularly inspect the revolver for any signs of wear, and consult a qualified gunsmith for any necessary repairs or adjustments.
Comparing the 646: Rivals and Relatives
The 646 is often compared to other revolvers, particularly those in the L-frame family. The Smith & Wesson Model 610, chambered in 10mm Auto, is one possible comparison. Another comparison would be the Ruger GP100, renowned for its strength. The 646 competes against semi-automatic handguns chambered in .40 S&W.
Customizing Your 646: Enhancements
The Smith & Wesson 646 supports customization to enhance its performance and tailor it to individual preferences. Aftermarket grips are available in a variety of materials and designs to improve comfort and handling. Upgraded sights, from fiber optic front sights to tritium night sights, are another option. These custom options give the owner the ability to further personalize and maximize the utility of their firearm.
Finding Your Own 646: Purchase Considerations
The Smith & Wesson 646 can be found through a variety of channels. Local gun stores are a good place to begin your search, allowing you to inspect the revolver in person. Online retailers often offer a wider selection and competitive pricing. The used market is also a viable option, providing an opportunity to acquire a 646 at a potentially lower price. Be sure to check for safety and proper function.
In Conclusion: A Lasting Impression
The Smith & Wesson 646 is more than just a firearm; it’s a testament to the enduring appeal of the revolver. Its robust stainless-steel construction, reliable action, and the potent .40 S&W cartridge combine to create a potent package.
