Hmm gonna have to disagree about a handgun being easies to use than a sword in a fight. It's definitely much easier to threat, hold off and hurt someone with a pistol than with a sword, since you just have to move your finger and get a chance to severely injure or kill someone (I say that as someone who already fought in a sword fight. They are tough to even move!)
Otherwise, yeah. Thosr uses for First Aid make sense. It's just my CoC head thinking something else.
