Introduction
Investigations related to firearms include forensic firearms examinations, gunshot residue analysis, wound examinations, and shooting reconstructions. Forensic firearms examinations encompass the analysis of the firearm and ammunition, such as firearms operability testing, microscopical bullet and cartridge case comparisons, and serial number restorations. Gunshot residue examinations consist of the chemical, microscopical, and spectroscopic examinations of residues that result from discharge of the ammunition within the firearm, specifically the primer and gunpowder. Gunshot residue examinations are...
