Lady Godiva and Erik, I really appreciate your replies. I'm not sure that ankle carrying is going to be the best choice for me, but I decided to at least pursue it and see what it's like. I can buy a rig online that is pretty inexpensive, and can at least get a taste of it.
Though speed and efficiency can indeed mean everything when it comes to drawing a gun within the confines of a grave situation, I have not been focusing on that aspect of carrying concealed. It has been my thought that simply having a gun available very quickly is far better than having none at all. Thus I've been of the mindset that an ankle holster might be "as good as any."
You good folks have given me some food for thought and I will proceed, better prepared and more knowledgable for having posted here. This place rocks!
