You are absolutely correct, you are far more likely to need to administer first aid to someone than you are to shoot someone, and the most likely person you will need to render first aid to will be a family member or friend. I get first aid/cpr training every year at work. I have a first aid kit, cpr protective barrier and gloves at home and in all my vehicles. I have had occasion to use my first aid kit twice in the last few years, but I've never had occasion to use my gun. I will still continue to carry both every day though.
