Based on an analysis of legal regulations and collected data on the processing of cases of domestic violence in which firearms were used to commit crime, this study provides a critical review of the response of the criminal justice system and identifies areas where action is needed to reduce the risk of firearms misuse related to domestic violence. Key legal gaps and obstacles in the implementation of existing laws have been mapped, as well as institutional shortcomings in the knowledge and awareness of professionals regarding the link between firearms misuse and gender-based violence. The collected data should provide a basis for improving the knowledge of professionals in the criminal justice system about the risks and consequences of firearms misuse in the context of domestic violence.
