AFTE Store - Glock Marking Barrels – An Evaluation of Individual and Subclass Characteristics

Glock Inc. recently replaced the Enhanced Bullet Identification System (EBIS) with what Glock refers to as the Glock
Marking Barrel. Casts and test fired bullets from thirty-five Glock Marking Barrels were evaluated for subclass and
individual characteristics. It was determined that the barrels had subclass carryover from barrel to barrel manufactured
using the same mandrel. However, identification of a fired bullet back to the barrel/firearm that fired it was still possible
using specific areas of the fired bullet. Due to the fact that this type of barrel will be used in all models of Glock pistols, an
examiner should be aware of which areas of a fired bullet may have a high potential for subclass characteristics.
