What safety measure should be taken when handling a runaway gun?

Pointing the gun downrange is the most appropriate safety measure when handling a runaway gun. This practice is crucial because it ensures that if the firearm discharges unexpectedly, the shot would go into a safe area, minimizing the risk to people and property. Keeping the muzzle pointed downrange is a fundamental rule in firearm safety, prioritizing the protection of individuals in the vicinity.

Considering the other options, immediately removing the magazine is important in many contexts, but if a gun is runaway, simply removing the magazine will not necessarily stop it from firing. Disassembling the firearm could be dangerous while the weapon is hot or active, and it may not be possible to do safely in that moment without first ensuring the gun is secured. Lastly, firing at will to relieve tension is irresponsible and poses a significant safety risk, as it could result in unintended injuries or damage. Thus, directing the gun downrange remains the best course of action to ensure safety when handling a runaway gun.
