The Smith & Wesson Model 638 Airweight is a refined version of the classic Model 38 Bodyguard, combining the tried-and-true aspects of its predecessor with modern enhancements to suit today’s defensive needs. This revolver features a lightweight alloy frame that ensures ease of carry, crucial for a concealed carry handgun. Its stainless steel barrel and cylinder are designed to withstand the rigors of regular use, especially important when rated for continuous +P .38 Special ammunition. The Model 638 is distinct for its snag-free enclosed hammer, allowing for safe and unimpeded withdrawal from holsters or clothing, a crucial feature for a self-defense weapon. Further improving its utility, the Model 638 supports both single-action and double-action functionalities, offering versatility depending on the situational need. While training typically advises against thumb-cocking the hammer in tense scenarios, the option to use a lighter single-action trigger pull can be beneficial in controlled settings where precision is required. The revolver maintains a compact and manageable size with a 1.875" barrel and a total length of 6.3", making it an excellent choice for personal defense. It features a synthetic boot-style grip and standard notch rear and serrated ramp front sights, which aid in quick sight alignment and target acquisition. Weighing just 14.6 oz empty, the Model 638 is a blend of portability, functionality, and reliability, designed to meet the needs of modern-day users.
