My life is valuable to me, enough so that I will pick the best tool for the job of defending it. A SA is not the best tool for the job. I choose to practice SD scenarios with a glock 19. The S.A. is for playtime, range time, and woods carry. The G19 is for social situations. I don't waste my time practicing for SD scenarios with a S.A. because that boat sailed over 100 years ago.
