What information is required for the E-TRACE application?

The correct information required for the E-TRACE application includes details such as the make, model, serial number, and caliber of the firearm. This specific information is crucial as it allows law enforcement to trace firearms back to their original purchasers and understand their history in terms of ownership and potential illegal use. This detailed data helps establish a paper trail that can connect firearms to crimes and assist in investigations.

While other options may seem relevant, they do not provide the necessary operational data needed for tracing firearms effectively. For instance, the purchase date and location might offer context but are not as critical for identification as the firearm's specifications. Similarly, a buyer's social security number is sensitive personal information that is not typically required for tracing purposes, and the type of firearm safety features does not contribute to tracing the ownership or history of the firearm. The focus is primarily on the make, model, serial number, and caliber since these are unique identifiers that serve as the foundation for tracing a firearm’s journey through sales and ownership.
