AFTE Store - Case Report: Ejection Port Marks: A Signature of Beretta

A useful class characteristic was observed on cartridge cases fired from two .40 caliber Beretta pistols. In a recent case where traditional marks were found to be insufficient, identification was possible only through ejection port marks. These marks are generated as the cartridge case is ejected from the firearm’s action and strikes the edge of the ejection port as it exits the firearm. Reproducible ejection port marks were observed on fired cartridge cases from numerous Beretta pistols of various models and caliber.
