Also, guns are designed to be easy to use. Point at target, pull trigger, target has a hole in it. Reloading? Pull out box, put in new box.
Tell me, have you ever operated a firearm in your life? As someone who has, its a case of nice idea, but its not that simple. You point firearm at target, pull trigger, and miss unless you have some decent training.
As for the military training, in order to become a qualified surgeon-grade doctor, you do sacrifice the ability to be a combatant-grade military officer. You simply don't have the time to learn how to pull someone to pieces and put them back together, and still have time to hone your ability with a firearm. Even within the canon, the doctors were non-combatants for the most part.
