This comprehensive review of the S&W 638 aims to provide the detailed, technical insights you need to confidently evaluate if this revolver aligns with your personal safety requirements and lifestyle.

Understanding the S&W 638: A Closer Look at Its Design

The Smith & Wesson Model 638, part of the venerable J-Frame series, is engineered specifically for concealed carry and personal defense. Its design incorporates several key features that address the concerns of prospective permit holders, particularly those prioritizing safety and ease of use. This revolver blends traditional reliability with modern carry considerations.

Airweight Frame and Materials

The S&W 638 features an aluminum alloy frame, earning it the “Airweight” designation. This material choice is crucial for reducing the overall weight of the firearm, making it significantly more comfortable for all-day carry. The cylinder, however, is constructed from stainless steel for durability and safe operation under pressure.

Shrouded Hammer Design

Perhaps the most distinctive feature of the 638 is its shrouded hammer. This design element encapsulates the hammer within the frame, preventing it from snagging on clothing during the draw. It offers the best of both worlds by allowing for both double-action (DA) and single-action (SA) firing modes.

.38 Special +P Caliber

Chambered in .38 Special, the S&W 638 can also safely handle +P ammunition. This flexibility allows users to choose between standard pressure rounds for practice and more potent +P defensive loads for enhanced stopping power. The five-shot capacity is standard for this compact frame size.

• Caliber: .38 S&W Special +P
• Capacity: 5 Rounds
• Barrel Length: 1.875 inches
• Front Sight: Integral
• Rear Sight: Fixed
• Grip: Synthetic
• Weight: 15.1 ounces (empty)
• Overall Length: 6.3 inches

Ergonomics and Concealability: Is It Comfortable to Carry?

A firearm’s comfort and concealability are paramount for any concealed carry permit holder. The S&W 638 excels in these areas due to its compact dimensions and lightweight construction. Its design minimizes printing, ensuring discretion.

Weight and Dimensions

Weighing in at just 15.1 ounces unloaded, the 638 is remarkably light. This low weight is a significant advantage for all-day carry, reducing fatigue and making it suitable for various carry positions. Its short barrel and overall length contribute to its compact footprint.

Grip and Handling

The factory-installed synthetic grip on the 638 is designed for a balance of concealment and shootability. While compact, it provides a secure hold for a small revolver. Many users opt for aftermarket grips to enhance comfort and control, especially for larger hands or extended range sessions.

Carry Options

The S&W 638’s small size makes it highly versatile for multiple carry methods. Its shrouded hammer is particularly beneficial for pocket carry, preventing snags. Inside-the-waistband (IWB), outside-the-waistband (OWB), and ankle carry are also popular and effective options. Here’s a comparison of the S&W 638 with another popular lightweight concealed carry revolver:

Trigger Mechanics and Shootability: Addressing the Learning Curve

For potentially less experienced shooters, the trigger pull of a revolver, especially in double-action mode, can present a learning curve. Understanding the 638’s trigger characteristics is key to mastering the firearm. The shrouded hammer offers a unique advantage here.

Double-Action/Single-Action (DA/SA) Operation

The S&W 638 operates in both double-action (DA) and single-action (SA) modes. In DA mode, pulling the trigger both cocks and releases the hammer, resulting in a longer, heavier pull. For SA mode, the hammer can be manually cocked, leading to a much lighter and crisper trigger break. This SA option is a distinct benefit for accuracy.

Trigger Pull Characteristics

The double-action trigger pull on a J-Frame is typically heavy, often in the 10-12 pound range. This heavy pull is a safety feature, reducing the chance of accidental discharge. However, it requires practice to shoot accurately. The single-action pull is considerably lighter and shorter, usually around 3-5 pounds, offering greater precision for deliberate shots.

Recoil Management for New Shooters

Given its light weight and .38 Special +P chambering, the S&W 638 produces a noticeable recoil impulse. For new shooters, this can be intimidating. Proper grip, stance, and follow-through are essential for effective recoil management. Starting with standard pressure ammunition for practice is highly recommended.

Tips for Trigger Control and Recoil Management

• Dry Fire Practice: Regularly practice dry firing (with an unloaded firearm and snap caps) to smooth out the DA trigger pull and build muscle memory.
• Strong Grip: Employ a firm, two-handed grip to mitigate recoil and maintain control.
• Stance: Adopt a stable shooting stance to absorb and manage the recoil effectively.
• Focus on Front Sight: Maintain focus on the front sight post throughout the trigger pull and shot.
• Start with Standard Ammo: Begin range sessions with standard pressure .38 Special rounds before transitioning to +P ammunition.

Safety Features and Reliability: Your Peace of Mind

The reliability and inherent safety of a firearm are non-negotiable for personal defense. The S&W 638, building on the J-Frame legacy, offers both. Its design prioritizes safe handling and consistent performance.

Shrouded Hammer Safety Benefit

The shrouded hammer of the 638 serves as a significant safety feature. It protects the hammer from accidental snagging on clothing or other objects, preventing unintended cocking or discharge. This design is particularly advantageous for pocket or deep concealment carry.

Proven J-Frame Reliability

Smith & Wesson J-Frames have a long-standing reputation for reliability. Their simple, robust design means fewer parts to malfunction compared to more complex semi-automatic pistols. This mechanical simplicity translates to dependable operation under adverse conditions. Revolvers are generally less susceptible to ammunition-related stoppages like “stovepipes” or “fail-to-eject.”

Safety Protocols and Best Practices

While the 638 incorporates design safety features, user adherence to fundamental safety rules is paramount. Responsible firearm ownership involves continuous education and disciplined practice.

1. Always Treat Every Firearm as if it Were Loaded: This is the cardinal rule of firearm safety.
2. Never Point the Muzzle at Anything You Are Not Willing to Destroy: Maintain muzzle control at all times.
3. Keep Your Finger Off the Trigger Until Your Sights Are On the Target and You Have Made the Decision to Shoot: This prevents accidental discharges.
4. Be Sure of Your Target and What Is Beyond It: Understand your backstop and potential collateral damage.
