Hi: I've been casualy looking at gun safes as a place to store guns of course and important paper stuff and it seems the fire ratings are all over the place with the most popular 1400 degrees for 30 mins. is this adequate? i don't need a real big one 10 or 12 gun size is plenty good but it seems the bigger they get the better fire rating is and price and weight, what is a rating that is adequate? and maybe some brand names, suggestions? John
