Are you willing to share what brand the safe was? I'm just questioning my choice.
It doesn’t matter. When the fire is hot enough no gun safe will save the firearms.
About 20 years ago we built a new house to replace one burned down in the High Park fire. The owner was very involved in cowboy action shooting and had five gun safes. He showed us photos of the aftermath.
Three gun safes blew the doors open and were shaped like bowling balls, the other two the doors held but were still shaped like bowling balls.
He had a plastic bucket with about 50 lbs of silver coins in one safe. The silver was a big slag, with some coins melted into the slag a guy could still identify.
