The model 642 was introduced in 1993 and it is the most favorable J-frame on the market closely related to the Smith & Wesson 442. J-frame revolvers have been around since 1950 and represent the smallest-frame wheel revolvers on the market. The finish is the only difference between 442 and 642, in fact, the 442 features a black finish, while the 642 has a silver finish. The 642 model is a lightweight gun of 14.4 ounces only. The frame is made of aluminum alloy, and the cylinder and barrel are stainless steel. This model, as 442 as well, is using .38 special caliber only and has a 5-round capacity. The barrel is extremely short, 7/8 inches. With this gun, you will get less recoil and less muzzle flash as well, so it’s a great choice even for a beginner. The sights are pretty standard, the front sight is milled into the barrel, and the rear one I milled into the top of the frame. The trigger is double-action. The grip is, of course, minimal but it is adjustable. Overall, this is a small-size, lightweight, great concealed carry, self-defense manufactured pistol.
