4safety, first welcome aboard. I vote for keeping one of the shot guns as a home defence weapon. Revolvers are, by design, very reliable. As for a self defence weapon in revolvers, I don't think I would go below the 32 Magnum. Read this short article: http://www.gunblast.com/Taurus_UltraLite32.htm
Good luck in your search, and please let us know what you decide.
Y'all be safe now, ya hear!
