Browning
I have four Browning Pro-Steel that are all dial, no key lock and set to the same combination. That combo. is not written down anywhere in the house. I do know of an aquaintance that had his number written down behind a picture on the wall. They found it.
Several of my friends have the number-no name in their safes for emergencies.
Protection? I know that when I come home, if the safes are empty, I do not have to go checking the local pawn shops. I think the stats show that most burglaries are commited by 18-25 yr. olds looking for something to sell for drugs. My safes protect me from that.
In fact, I have a coffee can 2/3 full of change sitting beside two of them. My theory ( luckily untested so far ) is to make the thief happy. Yeah, he can't get into the safes, but here is cash money right in front of him and it takes two hands to carry out. The added bonus? is that it is a good way to know if someone has been in.
The reality is that if your collection has enough value to attract pros, you will probably be dealing with them holding a weapon on you or a loved one and forcing you to help load them into their rig.
For the past 25 years, I have ALWAYS loaded and unloaded guns in my garage. I am not selling guns in the neighborhood, so I see no reason to advertise them.
Some would call this paranoid, I call it common sense. To each his own.
