When we retired gave my old safe to a friend. Nice "Sun Welding" medium security 1100 lbs. But had a gated yard, close retired neighbors, house had unobscured outer view and quick police response. So just need something that would take a bit of time and tools to get into.
Now, way out in the boonies, property is gated, but only one house even visible from ours. Maybe 30-minute police response (county fire dept. is 2 miles away). Crooks could work on it a while. Whole different situation. House came with a "Winchester" safe in laundry room, so the best rifles are kept there. Put a really loud alarm on it.
I decided to go with an American Security safe for the handguns and valuables. Had a nice spot for it, color matched, and it seemed the best I could afford. Wasn't cheap, but 1-1948 Colt super 38 in original box/docs paid for it, so the other stuff can feel safe. Not bolted down, I had a buddy chastise me for that, till I told him it weighed 3500 lbs. empty. Have cameras in and out.
Lost my live security a few years ago, but I always used to worry bad guys would just shoot him, since no one would hear anyway. But if you didn't have anything, you probably wouldn't come in when he was here. If you were allergic to cats you probably won't stay long. About all we could do.
Like others have said, would be nice to have a gun cabinet like my Dad had. Those days are gone. Although I did see some gun rooms in LA that had steel jail like doors and alarms in the floors. Plus, they were counting on the quick response time of the PD, HA!
