The Smith & Wesson 640 is a compact, powerful revolver that has earned a solid reputation among law enforcement, concealed carry enthusiasts, and self-defense advocates. This in-depth guide will explore its features, history, performance, and more, providing you with a comprehensive understanding of this iconic firearm.
The History and Design of the Smith & Wesson 640
The Smith & Wesson 640, introduced in 1980s, is a member of the J-frame family of revolvers, known for their small size and concealability. It's built on the same basic design as the Model 10, but with some key improvements for modern use. This includes features like a shrouded hammer (which makes it more snag-free for concealed carry), and improvements in the overall strength and reliability of the firearm. The 640 solidified its position as a reliable and robust choice for personal protection. Its enduring popularity stems from its robust build, ease of use, and reliable performance.
Key Features of the Smith & Wesson 640
- Caliber: .357 Magnum/.38 Special. This versatility allows for the use of both powerful .357 Magnum rounds for self-defense and less-recoil .38 Special rounds for practice.
- Action: Double-action/single-action (DA/SA). This means you can either cock the hammer for a single-action shot (more accurate) or fire directly in double-action mode.
- Construction: The 640's frame is typically constructed from stainless steel, offering excellent durability and corrosion resistance.
- Capacity: It usually holds 5 rounds in its swing-out cylinder.
- Sights: Simple fixed sights are standard, although some models offer adjustable sights for greater accuracy.
- Size and Weight: Its compact size and weight contribute to its concealability. However, its small size may require a little more practice to manage recoil and achieve accurate shots.
Performance and Handling of the Smith & Wesson 640
The .357 Magnum caliber offers exceptional stopping power, making the 640 a formidable self-defense weapon. However, the .357 Magnum's potent recoil can be noticeable in such a small-framed revolver. This is something to consider, particularly for those with less experience or smaller hands. The use of .38 Special ammunition mitigates this problem, providing a more manageable recoil profile suitable for practice and less-demanding situations.
Recoil Management Techniques for the Smith & Wesson 640
Because of the potential for significant recoil, proper shooting techniques are essential for safe and effective use. These include:
- Proper Grip: A firm grip, high on the backstrap, is crucial to control recoil.
- Stance: Maintaining a stable stance reduces movement during firing.
- Follow-through: Keep your sights aligned and follow through after each shot.
Smith & Wesson 640 vs. Competitors
The 640 often competes with other small-frame revolvers, including the Ruger LCR and the Taurus 85. These revolvers each offer different features and trade-offs.
