Which item should be recorded when taking a firearm in as evidence?

Recording the serial number, make, model, and caliber of a firearm when taking it in as evidence is crucial for several reasons. Each firearm is uniquely identified by its serial number, which allows law enforcement to trace its history, ownership, and any past criminal activity associated with it. The make and model provide additional context regarding the firearm, which can be important during investigations, especially when matching evidence to crimes or known firearms involved in previous cases.

In contrast, while the weight of the firearm, the owner's name and address, and the location where the firearm was found may have some relevance in specific scenarios, they do not provide the fundamental identifying information necessary for the legal handling and processing of firearms as evidence. Properly documenting the unique characteristics of the firearm is essential for maintaining a clear chain of custody and ensuring that the evidence is handled in accordance with legal standards.
