What is one requirement for a lock-away safe for firearm custody?

A lock-away safe designed for firearm custody must be constructed of steel at least 2mm thick to ensure it provides sufficient protection against unauthorized access. Steel is a robust material that offers resistance to compromising attempts, such as forced entry or tampering. Thicker steel enhances this security further, as it is more difficult to cut or breach compared to thinner alternatives.

Other materials, such as plastic, lack the durability and strength required for securely storing firearms. Safes that can be opened without a key would defeat the purpose of secure firearm storage, as they would reduce the overall security level. While weight can be a factor in security, the specific requirement of at least 100 pounds does not universally apply to all lock-away safes, as some high-quality safes may weigh less yet still offer adequate security due to their design and construction materials.
