Smith & Wesson serial numbers can typically be found in several locations depending on the type of firearm. For handguns, the serial number is often located on the frame, usually on the right side or under the grip. For revolvers, it may also be found on the cylinder crane or yoke. For rifles and shotguns, the serial number is usually stamped on the receiver.
