    For this reason, forensic ballistics examiners may not fire more than five shots from a weapon found at a scene. [3] Known exemplars taken from a seized weapon can be compared to samples recovered from a scene using a comparison microscope as well as newer 3-D imaging technology. Striation images can also be uploaded to national databases.

    en.wikipedia.org/wiki/Microstamping

    Microstamping is a proprietary ballistics identification technology. Microscopic markings are engraved onto the tip of the firing pin and onto the breech face of a firearm with a laser. When the gun is fired, these etchings are transferred to the primer by the firing pin and to the cartridge case head by the breech face, using the pressure ...

    Forensic examiners use this test to determine the gun to target distance. This test is performed first because it does not interfere with the later sodium rhodizonate test. [ 7 ] The presence of nitrite ions is what triggers the colour change, and therefore we do not consider this test to be indicative of GSR.
