Safes (ANY BRAND or ANY PRICE) are made from steel. ANY STEEL can be cut through with an Angle Grinder, a Sawzall, or similar like a sharp knife through a block of Cheese. I've got some pretty powerful Angle Grinders and cutting wheels that will go through really thick steel - the only question is are thieves, junkies, burglars going to have the brains, patience, time, balls and know-how to use them correctly or at all to get into your safe? Most likely, if a burglar can't readily open up a safe, he is probably just going to forget about it - unless he knows that person is away fro an extended amount of time. DO NOT post on Social Media sites - your vacation plans, travel times or destinations!! It's like an invitation for trouble these days!
That is WHY it is a GOOD IDEA to keep your safe in a locked and alarmed closet (separate keypad and code) and keep it out of sight of repair men, delivery men, visitors, guests, etc. That is also why I think the fancy paint jobs and pin striping is a big waste of money - since a proper safe will be securely bolted down and alarmed in an out of sight location. That is why I constantly advise guys here on this forum to look at used Jewelry safes which are ugly (as compared to a "gun safe") but much much stronger and much harder for a burglar to break, cut or pry. They carry a much better UL Burglar Rating also!
There is NO SUCH THING as a Burglar Proof safe - it's just that the better ones take longer and a more concerted effort to crack opened. If Bank Vaults can be broken into - a pro will get into any of our gun safe with ease. The thing is that MOST Pro's will not really be out to target home owners as opposed to highly rewarding targets. Most of us are "small potatoes" compared to large estates, banks, jewelry stores, etc.
The job of a good gun safe is to keep kids and unwanted visitors out, afford some level of fire protection, and to give the owner piece of mind. If anyone here os looking for a 100% break-in proof safe - - you will have to ask Fort Knox Kentucky if they have extra space for your firearms collection! And for Pete's sake....... BOLT 'EM DOWN, ALARM 'EM, AND KEEP THEM OUT OF SIGHT! That is your BEST protection against unwanted entry!
