Here is how it goes real world. First a guy is a target shooter to get the right habits for safety, storage, handling and yes shooting skills. He practices dry fire and sight picture etc at home. Handling. Then as he gets better he takes tactical type training, the diff being more use of force law lessons and a somewhat more sophisticated kind of shooting. Like from behind concealment like a door or wall.

And if we really want to do the big thing that makes a big diff in gun deaths, get the heck after the gangs that are having gunfights damn near daily. Double positive-You reduce both deaths directly and reduce the practical necessity of a violent defense for the good guys in the area.
