What does direct control over a firearm imply?

Direct control over a firearm implies that the firearm is within the visual field and physical reach of the shooter. This means that the individual can maintain awareness of the firearm's location and status at all times, which is crucial for ensuring safety. When a firearm is in direct control, the shooter can prevent unauthorized access, respond immediately to any unsafe situations, and handle the firearm responsibly.

The other options suggest scenarios where the firearm may not be readily accessible to the shooter. For example, locking a firearm away or placing it in a storage facility means that the firearm is not within direct control, as it cannot be accessed immediately or monitored directly. Similarly, having a firearm solely handled by an instructor does not place it in the personal control of the individual, making them unable to directly manage the firearm. Therefore, the essence of direct control is about immediate accessibility and awareness, which is best represented by the correct choice.
