NSSF Factsheet: Microstamping

Microstamping is a patented process that micro-laser engraves a unique alpha-numeric code on the tip of the gun’s firing pin so that, in theory, it imprints the information on discharged cartridge cases. Microstamping is not ready for use as a crime solving technology. That’s the conclusion of a peerreviewed study published in the scientific journal of forensic firearms examiners based on work conducted by a team of experts and funded by the U.S. Department of Justice. The patent holder of the technology, Mr. Todd Lizotte, was himself involved in the research 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.”
