Whereas California has implemented and amended a law requiring firearms manufacturers to micro laser engrave a gun’s make, model, and serial number on an internal part of each semiautomatic pistol so that, in theory, the information is imprinted on the cartridge casing when the firearm is fired; Whereas other States and the District of Columbia are considering similar mandates; Whereas, based on the current state of this nascent technology, it is impossible to microstamp a firearm cartridge and have the required identifying information legibly and reliably imprinted on the cartridge casing when fired; Whereas the scientific literature concludes there is no existing microstamping technology that will reliably, consistently, and legibly imprint the required identifying information from the tip of the firing pin of a semiautomatic pistol onto the cartridge casing it fires; Whereas one study found that the impressions were not decipherable nearly 50 percent of the time; Whereas the holder of the patent for the technology was a coauthor of peer-reviewed study that concluded, legitimate questions exist related to both the technical aspects, production costs, and database management associated with microstamping that should be addressed before wide scale implementation is legislatively mandated ; Whereas a subsequent study noted the use of expensive scanning electron microscope (SEM) technology still failed to solve the problems associated with microstamping; Whereas the microstamping process is costly and time-consuming, and threatens the employment of thousands in the firearms industry; Whereas the passage of legislation requiring its use would raise the cost of legal firearms by hundreds of dollars per gun for both law-abiding citizens seeking to exercise their Second Amendment right and for United States law enforcement personnel
