Well no but a gaming instructor will get your gun skills up faster imo. SD instructors are more about tactics & short range point shooting. Some of the best gaming shooters in the world train police & military for a reason. Like fof doesnt teach upu how to shoot bit how to not get shot, diff things, bith useful in a fight.Training, but a style that is applicable to why you are shooting. If it's primarily for gaming, go with a gaming instructor. If it's defense, go with a defensive shooting instructor. They are not the same thing.
