There may of course be circumstances in which a small caliber firearm must be pressed into service for self defense. If all one has at a time of need, one will need to make do with what he has. If one has physical limitations, one must make do with what he can manage.
But one also needs to be realistic about the limitations of that cartridge choice. He is trading possible effectiveness for other attributes -- such as that it's what he has or it's all that he can manage.
