Get a safe!
My $0.02 is that it may be easier to break into your house than you think. 15 years ago my wife and I were renting a place down in Denver and it was broken into in broad daylight. The thieve(s) simply brute-forced the front door open even though the door chain, knob and dead-bolt were locked (we typically came and went through back door, which was also locked except for the inside chain). Maybe the thieve(s) were pretty fat, pretty strong or pretty whatever, the door was forced open with the jambs, molding and woodwork where the dead-bolt seated were shattered. All done at about 9:00 in the morning on a busy urban street, and nobody saw nuttin'.
My S&W 469 was taken right off of the waterbed's headboard (hey, no laughing or waterbed remarks, it was 15 years ago!) where I kept it so I could get to it quickly. Another pistol that was not so pretty was left on the floor and my shotgun was left by the front door, apparently because it was too hard to hide in a summertime "smash-and-grab" job, or at least that is what the investigating cop said. I feel bad to this day that my 469 ended up in criminal hands to be used in who knows what kind of activity.
Now I have a quick safe in my closet that holds 2 - 3 pistols. Other pistols and long guns are at my dad's in his big safe. When I'm home, my CCW is usually in the truck in a locked garage, but sometimes inside with me. I can get to my safe and open it quickly for other weapons if needed for home protection.
If you are home, the common thief will know this and have little stomach for a confrontation that could become complicated. If you are not home, thieves will be brazen and seem to understand that even if a neighbor sees them forcing a door, the neighbor will take time to process what they see, take some more time to call "911" and even more time will go by before there is a police response. There is plenty of time for them to go through your home looking for valuables. Don't leave guns laying around where these guys will find them while tossing you house. Even some places you feel are well hidden will be discovered when the thief is simply pushing things aside onto the floor, pulling over bookcases, pulling out drawers and emptying them. If they find something lethal, the worst case is they'll use it against you if you happen to come home during their "job". However, if it is the typical smash and grab, they have no time for any kind of safe that cannot be simply carried off. Since the thieves want to get in and out quickly, they will just move on to something they can take away easily.
That's all I have to say about that.
