My $.02...which ain't worth much. There are some of us who, for whatever reason, can't carry any other way. We need to be dressed appropriately, shirttail tucked in, don't always wear a jacket, and the tuckables often print, get "untucked", bulge or are just plain uncomfortable. That being said, at the very least a "good" ankle holster is one of the few options that enable one to always have a weapon close by. Surely at the bottom of the list of carry options, but it's an option non-the-less.
