The streamline, lightweight, no-snag design of the Smith & Wesson Model 638 Airweight makes it an ideal concealed carry double-action revolver. The shrouded hammer of the 638 eliminates the risk of the hammer getting snagged on clothing, holsters, or purses when drawing the weapon in a self-defense situation, though still allows the shooter to cock the revolver for deliberate, precise aim. Shooting in double-action mode makes the 638 extremely fast to deploy in stressful situations, as there is nothing to remember to do except point and pull the trigger. The low profile, ramp front sight and the fixed notch rear sight are quick to line up, and the inherently ergonomic design, and synthetic finger-groove grips aid in the gun's natural pointability. The Model 638 is built on Smith & Wesson's famous J-Frame; it has a 5-shot cylinder rated for +P .38 Special ammunition. Stainless steel and alloy construction resist corrosion caused by humidity and perspiration when the revolver is carried close to the body. The Smith & Wesson 638 Airweight Double-Action Revolver carries easily, deploys rapidly, and has enough firepower to handle any self-defense scenario. Made in USA.
