What's Included
- Smith & Wesson Model 642-1 Airweight revolver
The 642-1 uses an aluminum-alloy frame to keep weight down while pairing a stainless steel barrel and a matte stainless, fluted cylinder for durability. The matte silver finish complements the enclosed-hammer profile and reduces glare.
This DAO revolver uses the Centennial-style internal hammer for a snag-resistant draw and consistent double-action trigger use. It is chambered in .38 Special and is rated for +P ammunition, offering flexibility in defensive loads.
The barrel measures 1.875 in, and the revolver carries five rounds in its fluted cylinder. Sights are fixed, with a serrated ramped front and a top-strap groove/notch rear for a simple, reliable sight picture.
Factory-style details include the black textured rubber boot grip with S&W logo medallion, Springfield, MA and S&W U.S.A. markings, and the 642-1 model stamp inside the yoke cut. No internal key-lock hole is present on the frame.
