The Smith & Wesson Model 642 Airweight (SKU: 103810) is a premier, ultra-lightweight J-frame revolver purpose-built for dependable concealed carry and personal defense. Constructed with a high-strength aluminum alloy frame mated to a durable stainless steel barrel and 5-round cylinder, this compact firearm weighs a mere 14.4 ounces empty, ensuring comfortable all-day carry without sacrificing structural integrity. As a member of S&W's iconic Centennial line, it features a completely enclosed, internal hammer operating exclusively in double-action-only (DAO), which provides a snag-free draw from pockets or holsters and prevents dirt or debris from entering the action.
