I haven't shot the 9mm version, but I have the .40 model. Fun is a good adjective for it. It was distinctly quieter than a .40 pistol. Easily more accurate than a pistol. Not a precision rifle, but "good enough" for pack or truck gun work. If one could get one for $400 or less, I'd do so. But not worth $500-$600 they seem to go for.
