"Since I don't really expect anyone to brake into my home office, located in the nice neighborhood in the middle of the day I don't really need a loaded gun."
Not to pick on you about this, just to give you some perspective...
Break-ins and other bad things happen ROUTINELY in nice neighborhoods, in the middle of the day. Just a few weeks ago, an acquaintance of mine was held up at gun point in the middle of day, just down the road from me, in a very nice neighborhood. Two of my co-workers have had home invasions in the middle of the day. They live in nice neighborhoods not far from here. A neighbor just five houses down the street from me had her home ransacked and burglarized, in the middle of the day. These are nice white-collar homes. I could keep going, but you get the point.
If you like keeping your revolver unloaded for dry-fire practice, maybe this is a good reason to get another gun, perhaps a little more compact, that you keep loaded and concealed, preferably on your person, but at least readily accessible at all times.
What's the benefit of all that practice, if the gun isn't ready for use when you need it?
