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.
