Which of the following is one of the 10 commandments of firearm safety?

One of the key principles of firearm safety is to unload firearms when not in use. This commandment emphasizes the importance of treating firearms as if they are always loaded. By ensuring that firearms are unloaded when they are not actively being used, the risk of accidental discharges is significantly reduced. This practice is crucial in maintaining safety, particularly in preventing tragic accidents that can occur when firearms are mishandled or accessed by unauthorized individuals.

In contrast, the other options presented do not align with established firearm safety principles. Carrying a loaded firearm without a need can lead to unnecessary risk, while storing firearms in open view does not provide adequate security. Similarly, while pointing firearms at the ground may seem safe in some contexts, it is not a universally accepted practice for safe handling. The emphasis should always be on proper handling, storage, and use of firearms to ensure safety for all.
