I switched to a revolver a couple of years ago. The main reason is I like the longer heavy trigger pull for safety concerns vs a semi-auto. I am not a leo, and I think a revolver works well for self defense. Even though not the main reason I switched, there is some situations where a revolver is more reliable. For the first 5 or 6 shots at close range, I would prefer a revolver. In the last few years they have been 2 high profile shootings were the semi-auto failed after the first shot. The biggest advantage a semi-auto has is capacity. I carry a k frame snub, and i am aware i only have 6 vs 15 rds when I used to carry my Glock 19. I have about as safe a life style as you can have and I think a revolver is a safer, better choice for me.
