When you need a lightweight carry revolver, you turn to Smith & Wesson's small frame Airweight Series. They are the original aluminum, small frame revolvers chambered in .38 S&W Special +P. The 642 features an enclosed hammer for a snag-free draw, and a serrated ramp front sight for fast target acquisition. This stainless-steel and alloy-framed 5 shot revolver weighs a mere 15 ounces, yet proves to be extremely accurate with a barrel length of less than 2 inches. This double-action-only revolver has a ramped front sight with a rear groove. Its grips, its metal, and its bore are all in very good condition.
