A typical day for a Firearm Examiner involves examining firearms, cartridge cases, bullets, and related evidence to determine their origin or involvement in criminal cases. You will use specialized laboratory equipment, create detailed analytical reports, and may be called upon to testify as an expert witness in court proceedings. Collaboration with law enforcement officers, detectives, and other forensic specialists is common, as is maintaining meticulous records to ensure the integrity of evidence. The role requires balancing laboratory analysis with paperwork, meetings, and sometimes on-site investigations or courtroom appearances.
