When is it necessary to use a firearm lock?

Using a firearm lock is essential anytime the firearm is not in use, as this practice enhances safety by preventing unauthorized access and accidental discharges. This means when the firearm is stored, or not actively engaged in use, the lock acts as a critical safety measure, particularly in homes with children or others who should not have access to firearms.

In contrast, there may be specific situations where cleaning, transportation, or firing the weapon has required precautions, but these do not prioritize overall firearm security like the consistent use of a lock during periods of non-use. Also, during cleaning, a firearm might be temporarily unloaded but still poses a safety risk if not secured. Similarly, while transporting, using a lock is prudent but only addresses safety during transit rather than when the firearm is stored. Lastly, a firearm should never be secured with a lock while firing, as this would prevent its intended use and compromise safety by creating a potentially hazardous situation. Thus, locking a firearm is most necessary during all times it is not actively in use.
