AFTE Store - Glock’s New EBIS Barrel: The Finale to the Miami Barrel Saga

As Glock progressed in developing a barrel with identifiable markings, the Miami-Dade Police Department Crime Laboratory Bureau has examined improvements made by Glock in creating a barrel signature that is readily identifiable to the firearm examiner. Since the last publication, Glock has improved its tooling method creating a barrel that produces readily identifiable marks. This new method creates gross marks (possible subclass characteristics), allowing for quick indexing, and fine striations for improved identifications of test fired bullets. During the initial evaluation, sufficient individual characteristics were found for positive identifications. Durability testing revealed that the individual characteristics and the gross marks may change with wear; yet these barrels did prove to reproduce sufficient individual characteristics for positive identifications. Glock markets this new rifled barrel design as the Enhanced Bullet Identification System (EBIS).
