Smith & Wesson Model 638: A Comprehensive Review of the Airweight Bodyguard

The Smith & Wesson Model 638, often referred to as the Airweight Bodyguard, is a classic example of a lightweight, concealed carry revolver. With its shrouded hammer design and aluminum alloy frame, the S&W 638 offers a blend of reliability, concealability, and ease of use that has made it a popular choice for self-defense among law enforcement officers and civilian shooters alike. This article delves into a detailed examination of the S&W 638, exploring its features, benefits, and potential drawbacks.

Overview of the S&W 638

The S&W 638 is a small-frame, five-shot revolver chambered in .38 Special. It is part of Smith & Wesson’s J-frame series, known for their compact size and lightweight construction. The defining characteristic of the S&W 638 is its shrouded hammer, which allows for both single-action and double-action firing. This offers versatility in shooting styles and preferences. The “Airweight” designation indicates that the frame is constructed from an aluminum alloy, significantly reducing the overall weight of the firearm.

Key Features and Specifications

Caliber: .38 Special (+P rated)
Capacity: 5 rounds
Frame Material: Aluminum Alloy
Barrel Length: 1.875 inches
Overall Length: 6.31 inches
Weight: Approximately 15 ounces (unloaded)
Sights: Fixed front sight, integral rear sight
Grips: Various options available, typically rubber or synthetic
Hammer: Shrouded (allows for single and double-action firing)

Design and Construction

The design of the S&W 638 prioritizes concealability and lightweight carry. The aluminum alloy frame contributes significantly to its low weight, making it comfortable to carry for extended periods. The shrouded hammer is a crucial element, as it protects the hammer from snagging on clothing during drawing, a common concern with traditional exposed hammer revolvers. This design also provides the option of manually cocking the hammer for a lighter, single-action trigger pull.

Frame and Finish

The aluminum alloy frame is typically finished in a matte silver or gray color. While durable, aluminum alloy is not as resistant to wear and tear as steel. However, the reduced weight is a significant advantage for concealed carry. The stainless-steel cylinder provides durability and resistance to corrosion.

Grips and Ergonomics

The grips on the S&W 638 are often made from rubber or synthetic materials, providing a secure and comfortable grip. Aftermarket grip options are readily available, allowing users to customize the feel and ergonomics of the revolver to their preferences. Smaller grips enhance concealability, while larger grips can improve recoil management and comfort during extended shooting sessions.

Performance and Handling

The S&W 638 is designed for close-range self-defense. Its short barrel and lightweight construction make it easy to handle and maneuver in tight spaces. However, the short barrel also results in a shorter sight radius, which can make accurate shooting at longer distances more challenging. The recoil can be significant, especially when using +P ammunition, but is manageable with proper grip and technique.

Accuracy and Range

While not designed for long-range accuracy, the S&W 638 is capable of delivering accurate shots at typical self-defense distances (3-7 yards). The fixed sights are simple but functional, and with practice, users can achieve consistent accuracy. The short sight radius requires a steady hand and focused concentration.

Recoil Management

Due to its lightweight construction, the S&W 638 can exhibit noticeable recoil, particularly with +P ammunition. Proper grip, stance, and technique are essential for managing recoil and maintaining control of the firearm. Using heavier grips or adding a recoil-reducing grip can also help mitigate the effects of recoil. [See also: .38 Special Ammunition Guide]

Fixed Sights: The fixed sights offer limited adjustability, which may be a drawback for some shooters.
