Good point about hiding guns and repair people or burglars finding them. That's why I was leaning more towards bolt down quick access safes. 3 or so around the house in locations you wouldn't check might be a decent idea.
As for "carry", I do. However not 100% of the time I'm home. I bet few people carry 100% of the time they are home. Plus I was thinking more of my future non-carrying (yet) wife, if something were to arise while I was gone and she were downstairs when the alarm went off, she would have a gun nearby if need be.
