SUMMARYBallistic ID Tagging™Glock Project

The scraping action associated withGlock firing pins does not degradethe embossed ID informationafter 1400+ rounds.

Lacquered primers do not presenta problem. Ageing of fired cartridges followed

by cleaning does not presenta problem.

Misfired cartridges and variationsin peak pressure during dischargedo not present a problem.

Primer finish and hardness do not present a problem.
