AFTE Store - The Miami Barrel Saga Continues

The Electronic Spark Reduction Method which resulted in The Miami Barrel was not found to significantly enhance the identifiability of fired bullets. Glock was contacted by the City of Miami Police Department and was asked to further research and develop a new barrel. The Miami-Dade Crime Laboratory Bureau was asked to evaluate and report on the reproducibility of marks left by the new barrels. Glock developed a tool to create additional marks in the barrels. This tool created gross marks (subclass characteristics), allowing quick indexing and improved identifications of test fired bullets. Sufficient individual characteristics were found for positive identifications during the initial testing. Durability testing revealed that the individual characteristics and gross marks (subclass characteristics) failed to reproduce as they originally did. It was concluded that the changes made to the Glock barrels by the new tool did not render them readily identifiable.
