The Smith & Wesson Model 642 is a small, lightweight revolver chambered in .38 Special. It is designed for concealed carry and personal protection and is made with an aluminum frame and a stainless steel cylinder. The 642 is a “hammerless” design, meaning that it does not have a visible hammer spur. This makes it easier to draw from a holster and reduces the risk of snagging on clothing. Purchase now!!
