Slide 159mm Glock Firing Pin Impression after 1400 rounds Glock Firing Pin after 1400 rounds (image reversed) From a Study by Lucien Haag Presented to the National Academy of Sciences Slide 16SUMMARY Ballistic ID Tagging Glock Project The scraping action associated with Glock firing pins does not degrade the embossed ID information after 1400+ rounds. Lacquered primers do not present a problem. Ageing of fired cartridges followed by cleaning does not present a problem. Misfired cartridges and variations in peak pressure during discharge do not present a problem. Primer finish and hardness do not present a problem.
