Aims and objectives

The ENFSI EWG Firearms/GSR is the European organisation of experts in one of the most interesting disciplines of forensic science. – It combines scientific experience in the fields of firearms identification (FAID), firearms technique, gunshot residues (GSR) and scenes of crime reconstruction in firearms offences. According to the Terms of Reference (ToR), in compliance with the goals of ENFSI, world-wide associated members join in the annual meetings and the projects of the EWG Firearms/GSR.




EWG Firearms/GSR was founded in 1995 in Rijswijk. It is governed by a steering committee and consists of two subgroups:

  • firearms (FA)
  • gunshot residues (GSR)

The interests of these subgroups have an overlap. The Steering Committee consists of five members each from both fields of expertise (FA, GSR).
