It isn't true, browning will not cover contents on a break in to the safe or if it stolen.
I would recommend looking for a safe and buying it based on features. If you look based on price, and ever have a break in or a fire, you can be potentially pretty disappointed when you come home and find what has happened to the safe. Not to mention non UL listed locks can end up keeping you out of the safe as well with the high failure rates they carry.
Here is a safe that went through a fire, and everything inside survived. However, they didn't get the safe open until a week later, and some of the guns started to rust because of the steam introduced to the interior of the safe from the sidewalls heating up in the fire. It is very important to get the safe open right away after a fire, get everything washed down with hot soapy water, and re-oil all the guns. It was a 1 hour @ 1700 degree fire rating. The fire was so hot it melted off the steel dial lock, and the steel handle of the safe.
