I typically carry one of my S&W model 629 .44 magnum revolvers, of which I have a few with different barrel lengths. Given where I live and my general lifestyle, I figure that if I ever have to defend myself, there is a much higher probability that the aggressor will be a a bear or a wolf rather than a human, hence the need for a more powerful caliber like the .44 mag. Usually, I carry openly, but sometimes concealed, especially if I'm making a trip into town or something.
