AFTE Store - Intratec’s Faceted Firing Pin

Cartridge cases fired in most Intratec model Tec-9, Tec-DC9, and AB-10 pistols are reported by firearm examiners to have angled, or faceted, firing pin impressions. This research shows that the faceting is a product of safety/operating handle contact with the tip of the firing pin. Firing pin impressions made at intervals of repeated contact show that the microscopic characteristics of the firing pin will change.
