Title: Firing Pin
Description: NIST engineer Alan Zheng points to the firing pin impression, one of three marks impressed on the surface of a cartridge case when a gun is fired. The marks, also known as signatures, can act like fingerprints to identify a specific firearm and are key elements in NIST's standard casing, Standard Reference Material 2461.
