No, and not in my home.
I have three safes, excuse me RSC's. They are inexpensive Canon 24 gun models, weigh around 400 pounds empty, I think a 30 min. 1200 f fire rating, and are bolted to the frame of the house (2) or the slab (1). They won't stop real pro's, but then almost nothing will. I also have a monitored security system and wireless cameras and separate alarm for the room with the safes.
My insurance company thinks they are just fine and gave a discount for having valuables in a "safe", as well as a monitored alarm discount. I think these types are just about perfect, I got the last one on Black Friday this year on sale for $499 (regularly $799). They are light enough that me and a friend could move it into place, but tough enough that grab and go thieves won't be doing much grabbing.
In my experience most of the people bashing these as "RSC's", tin cans, etc. want to sell you a $5,000 real safe. If you have enough "stuff" that professionals are targeting your house you can probably afford to drop $5-20k on a real safe, but for the rest of us these seem fine.
