I bought one of these “Bighorn” safe’s about 8 years ago. Man oh man they have gone up in price...At the time I paid $500 but it’s more than that now. Also, later on I changed the electronic keypad and installed a “Sargent and Greenleaf” combination lock.
Remember, whatever these safes state that can hold immediately divide that number in half. Also, remember, these are very heavy so think about that before moving. If you do move it yourself, remove the door and all the sheetrock (fireproofing) from the internals.
These are not “bank vault” quality but they will help again the “smash and dash” type criminal.
Sorry—here’s the link for the Bighorn similar to what I have.
