Abstract

Any device of any kind that is built or modiöed to discharge a projectile of any kind using the force of an explosive or other types of energy is considered to be a örearm. The three basic components of a örearm are the breech, barrel, and stock. The öring pin and hammer are part of the breech. The öring is initiated when the hammer strikes the öring pin, which then forcefully impacts the percussion cap at the base of the cartridge containing the primary explosive substance. During this procedure, the öring pin leaves distinct markings on the percussion cap that help determine if the purported handgun can be positively or unfalsiöably identified during test öring. These markings, however, can occasionally be purposefully damaged or removed in order to lead the investigation officer or ballistic expert astray. Firing pin markings won’t be useful for identiöcation in these circumstances. The conceptual work in the current study involves using micro laser printing to engrave the serial number of örearms on the öring pin’s surface as well as precise markings at the öring pin’s tip. These carefully etched markings will make it easier to identify factory made weapons in shooting incident instances. However, the main goal of this effort was to increase the signiöcance of öring pin marks for the identiöcation and linkage of the öred cartridge case and örearm. Although there are other ways for identiöcation, such as breech marks, extractor marks, chamber marks, etc.
