Best weapon for Concealed Carry advise

you can see in the picture he is reacting to the thread, reaching for his own gun and at that very moment, he becomes a target
(now i know, you never draw on a drawn gun, but i dont think he had much of a choice)

fact of the matter is, he tried to reach his EDC and ended up dying because of it

so there is a concern there...one that can only be met with rigorous training

What kind of training can get you out of a situation like that? Kind of like 'what training can prevent you from being shot in the back?'
