A gun safe wouldn’t address the issue, did you read the article?

They are talking about negligent discharges caused by pulling the trigger on a gun without a magazine that had a round in the chamber and the gun doesn’t have a magazine disconnect. They are advocating for magazine disconnects to be required on all firearms, which is the wrong way to go about addressing the issue.

Proper safe handling of a firearm is how you prevent negligent discharges, a safe will have no impact on the scenario they brought up.
