1st thing is that any safe can be defeated. I've missed some good deals on used tl15 and 30's due to cashflow.
If I was buying a NEW safe I would look at
Gun Safes : Fire Safe Manufacturer : Sturdy Gun Safe
They do have a great product and yes, built here in the states. Please watch his vidios. I will upgrade my amsec to a sturdy when I can.
2nd, a safe is only part of the plan. You need to keep it out of site from anyone that comes into your home. You also need to make sure that they can not cart it of somewhere else to open it. Mine is bolted into my homes 1 1/2" tounge and grove flooring with 1/2" lag bolts. It's stuck into a corner to prevent pry attacks on the door seams plus to deny 3 sides to fire and attack. next it's in a closet so that it's harder to work tools around. When my safe door opens it sends an alert to my cell as well.
Most of us have worked with metal. we know what it takes to bend,cut and rip apart things. Most safes are too weak!
