I stage several handguns in the living room/kitchen area, all in condition 1. Also a 16" M4 (semiauto) with 100-round drum and steel-core bullets in it and holo sight, near the top of the stairs, a 12-gauge with birdshot near master bedroom door, a 12-gauge with sabot slug and XD in master bathroom together with a compressed gas air horn (for summoning help, if the gunfire does not do that already). In my daughters' rooms they have another M4 and a pistol each (9mm and .380). Both my daughters shoot, and we practice break-in scenarios. My EDC G26 (G30 in winter) gets unholstered when I walk into the house, and I carry it upstairs when to change from street clothes, and they go on the night stand.
Two handguns I stage are located in places where I would run to if there was an intruder already inside the house (such as in a holster screwed into the back of the love seat, or in a holster screwed to the inside cabinet wall underneath the sink). My logic is if you are runnig for cover, have a weapon in the place you will cover at.
Oh, and the wife has a CCW and carries, too!
All my cars have a holster screwed into the center pillar (in the space next you drivers' right leg) and when entering a vehicle I transition from strong side carry to that holster. If I needed to draw while driving, I just lean forward slightly and reach for my peacemaker, no dicking around with seatbelts.
I have multiple surveillance cameras covering the entire perimeter of my house as well as multiple angles of each entryway (front door, back porch, and garage). We have a policy that it is not "polite" to visit someone unannounced after 8PM, and when the door is answered (after viewing the visitor on-camera), a gun is always at the ready.
Readiness condition goes from White to Yellow when the cameras show the motion-detector lights have come on, then from Yellow to Orange when someone is seen at or near the door. If necessary to answer the door, do not undo the chain bolt, have shoulder and foot pressing on the door to shut, handgun in hand with trigger finger high on frame. Strange persons or strange reason to be knocking? Speed-dial local PD non-emergency dispatch to report suspicious persons/activity, or press and hold 9 to autodial 911. If they barge in, recoil backwards, leap over the love seat where there is a solid oak bookcase and another gun underneath while yelling to other occupants of the house about the danger. Address the intruder and begin servicing the target. Nevada law permits the automatic use of deadly force in defence of the domicile, even absent a deadly force threat from the intruder. Surveillance cameras covering the foyer and living room also record everything.
When I am working in the garage with the door open, or in the back yard, a handgun is always nearby. But I do not carry holstered when at home.
11 November last year, me and the kids were watching TV in the living room when at 10:45PM the doorbell rang. At the first ring, threat condition jumps from White to Red. We determined in an instant that there was only one person at the door, he had a dark uniform, ball cap, some kind of equipment belt, a radio remote on his shoulder...looked like a young decent looking fellow, but you never know. Two cameras showed several people (not in any kind of uniform) walking in the street, and a cruiser with lights flashing across the street. One daugher went to the base of the stairs ready to bolt up to get the C1 M4 in the hallway, another daughter had her hand on her cellphone, while I answered the door with my G30 in my hand. It was local PD doing a house-to-house in search of suspects or information on a home invasion+sexual assualt and robbery on my street, about 12 houses away and around a bend in the road. Said they would like to view my surveillance video.
I agreed, still at Condition Red. Asked to see his badge and ID (event though he was in uniform, because I wondered about the 2 guys in the street in civvies). Allowed him into the house, going to Condition Yellow. Shoulda seen the look on his face when I opened the door with a gun in my hand, at my side behind my thigh, and walked to the dining room, placing the gun on the dining table. After a few minutes my daughter (who had gone upstairs before I let the cop in) came down and winked twice at me, our signal that all is OK. I did not know it at the time, but she called the local PD dispatcher and was told that they are saturating the area in search of the perp. Put gun on kitchen counter. Still at Condition Yellow, just in case. Then I began to show cop the video on a slave monitor in the dining room area. We eventually had 5 cops and 3 plainclothes detectives viewing the video, and I offered to show them how to use it and for them to take it to the station to examine at their leisure. They were able to get a license plate number of a vehicle similar to one used at a suspected-related crime, and eventually identified the perp, who has since fled to Mexico. When they returned my surveillance equipment, I got a nice thank you letter from the chief of the Neighborhood Crime Suppression Unit.
But, yah, I do not carry holstered at home, and I do state C1 firearms around the house, and we practice and discuss scenarios with the kids (I call 'em kids, but they are 23 and 19 this year). And for home defense, a shotgun is your best friend.
It is not enough to know how to use a gun. Preparedness in the home is more than that: it is both mental preparedness (develop and practice a plan of action with specifics that would vary depending on the nature of the threat) and physical preparedness (remember the difference between cover and concealment, and plan accordingly). Have a backup for every plan. Use methods of early-warning, such as motion-sensor lights all around the home, and consider a video surveillance system. Being able to identify subjects on the video is as important is being able to see them before they enter the house....one works best after the fact, the other is your alert level trigger. I have a system that displays on a slave monitor in the dining room, and a second DVR recorder located there that does NOT record any of my interior cameras...the primary recorder is elsewhere and records everything, and the primary is programmed to miss-call my cellphone 3 times in one minute if motion is detected in "alert zones" when nobody is home, then I jump online on my Android, log into the web interface, and view the video from anywhere in the world via the internet. I have made a "suspicious person" call to local PD while I was at work because of a person walking around my house....PD showed up (I was watching live via my cellphone) and it turned out to be a power company meter reader who couldn't find my meter....or maybe he was casing the joint for someone else? And no, I do not subscribe to any remote-monitoring service.
Keep in mind that the people you share your home with need to be as mentally prepared and as physically capable (of carrying out your defense plans and of using your firearms or other methods/devices) as you are. If not, it will do them no good when something goes down and you are not home.
When I read in the news about home invasions in and around my city and elsewhere, I wonder how the victims now feel about preparing a viable home defense plan and what their thoughts now are on gun bans and gun restrictions and the public perception (encouraged by leftist media) that gun owners are all potential homicidal maniacs. But then again, the barn always get locked after the horse has gotten out.
