I think safes are a good idea. They will protect your guns from some thieves.
I was talking about this with a couple of local officers and another customer one day. We have had multiple people come in to have me watch out for guns of theirs that have been stolen.
Something that happens way more than you would think is that guns left out of the safe are left alone, while the safe itself becomes the sole focus.
Here are a few stories:
1. We have a regular who collects American militaria and weapons, and rarer German WWII weapons. His collection is worth, conservatively, hundreds of thousands of dollars. He was doing an inventory of his collection and had them spread all over his living room so he could take pictures for his insurance company.
He and his wife went to church and out to eat, and while they were gone, someone broke into the house through the living room door, passed a veritable treasure trove of firearms, and went straight to the walk-in safe.
The door to the safe had been busted open and everything in it had been stolen.
All that was still in the safe was the junk this guy didn't care about; a Hi-Point, a couple of Glocks, a .22 Cricket, and some Zamac Saturday Night Special revolvers.
He was more mad about his destroyed safe than he was the guns.
2. We had another customer who had a rack full of guns in his living room. His burglars destroyed his bed looking for guns, then destroyed his locked metal gun cabinet/safe, and tossed every drawer and closet. They ignored the guns on display altogether.
3. One of the officers was telling me about a case where the owner had forgotten his combination after doing a collection-wide deep clean, and had laid every gun he owned on top of his large gun safe. Then he forgot to put them back away for a few days. Not a single one of those guns had been touched, but the safe had been broken into, and the burglars left empty-handed.
4. The other officer chimed in to tell me about a guy who had one of the electronic safes where the keypad had gone bad. The guy had been opening and closing the safe with the backup key, and had forgotten and left the key in the safe. His house was burgled and the people that broke in spent who-knows-how-long trying to pry the safe door open - not realizing they could have just opened the door. He thinks that when his wife came home they got scared off and left empty-handed. He had a loaded M&P Shield sitting atop the gun safe that wasn't touched.
I have other stories, but I have already been long-winded.
Anyway, I almost wonder if the best thing to have is an empty decoy safe and then a really good hidey-hole elsewhere.
Then again, maybe the criminals just wanted junk they could boost easily and intentionally disregard historical and hunting guns. Still doesn't explain cases like that 4th one.
