I have 2 cannon safes.. no issues in several years.. mine have the manual combo lock not the digital.. if you get one buy the de humidifier stick that goes with them..
I got the 48 gun cannon at tsc a few months back. To get 48 long guns in it you would have to take the shelves out if one side. I've been pleased with mine so far. 3 people and a appliance dolly got it in the house with ease. It dosent match up to a Liberty safe but this one was in my price range for the room I needed.
