I used my Governor for home defense. Loaded with .410 self-defense ammo. The pattern of the shot and discs on cardboard seemed quite effective - particularly for a head shot. Living in a 4 plex apartment with thin walls it seemed a wise choice of ammo to avoid hurting innocent neighbors if something happened. When I got too olde to manage a second shot well I sold the Governor and bought a Mossberg Cruiser pump shotgun in .410 (had the 12 gauge cruiser and it was a bit too much recoil at my age). I'm very confident .410 self-defense loads will do the job in my apartment defense setting.
And, as mentioned above, the large size of the Governor makes evil ones take notice and reconsider.
