I like more than one safe. That way if I get burgled, the burglars will be surprised and confused. They probably won't get one out let alone three.
Plus, I have different security levels for safes. Security costs big $. That's where big $ guns go. Ammo is at the bottom. Nobody is going to have the time or manpower to haul out all of my ammo, anyway. Keep in mind there are no laws requiring gun safes, ammo separate from guns, or any storage requirements whatsoever here. I just don't want my stuff walking.
I've also had a few run-ins with the local and regional cops. They know who I am and what I am hauling. They recognize me in public. They get an alarm call for break-in from my house and there will probably be about 5 departments responding in minutes. I remember one time a cop saw me carrying a firearm in what he thought was probably a suspicious manner. I was driving a car with a New Jersey plate (fleet vehicle) and such weapons or manners of carry would not be legal in Jersey. However, I know this plate number is known to them
He stood behind my car while I was in the store and kept one eye on me while calling in my plate number. Turned around and went back to his car and drove off. I have no doubt they told him, "Leave him alone. He's probably not breaking the law. We ran into him before and it didn't end well. If you have PC he is actually breaking the law, you are going to need backup."
anyhow I'd love a collection that requires me to have 3 safes.
