Which of the following is an important aspect of firearm safety?

Always assuming a firearm is loaded is a fundamental principle of firearm safety. This approach emphasizes the importance of treating every firearm with the utmost respect and caution, regardless of one's familiarity with it or whether they believe it to be unloaded. This mindset helps to prevent accidental discharges and encourages safe handling practices. By maintaining a belief that a firearm is loaded, individuals are more likely to engage in safe behavior such as pointing the muzzle in a safe direction, keeping their finger off the trigger until ready to shoot, and being aware of their surroundings.

While other aspects mentioned, such as using firearms only in target practice, knowing how to clean firearms properly, and keeping firearms locked away after every use, contribute to overall firearm safety, they do not embody the critical principle that underpins all safe firearm handling. Assuming a firearm is loaded serves as the foundation of safe practices and helps instill a consistent, cautious approach in all situations involving firearms.
