Glock Inc. recently replaced the Enhanced Bullet Identication System (EBIS) with what Glock refers to as the Glock Marking Barrel. Casts and test red bullets from thirty-ve 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, identication of a red bullet back to the barrel/rearm that red it was still possible using specic areas of the red 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 red bullet may have a high potential for subclass characteristics.
