If it has any impact on your decision, I have a Revolution 18 and I like it. I happened to get a really good deal on mine, otherwise I would have gone with the 24. You can get a Liberty door organizer from Amazon for about $90. I also like that the Revolution series has dials instead of electronic locks.
Don't waste your money on the magnetic panels that nail into the door; they are NOT strong enough to hold loaded mags, I don't care what the packaging shows.
Abel's in Huntsville has a Browning, I think, 24 gun safe with a 30 min fire rating at 1400 for $699.... Able's has great prices on their safes overall
Hey Mike I just bought a Winchester 26 gun safe at Tractor Supply in Tomball on sale for 594.00 + tax.
I think it was rated at 1200 or 1400 degrees for 30 min.
