Back when these guns first came out I had a brief email discussion with Wilhelm Bubbits the designer of the series. He mentioned the subcompact XS at that time and didn't think it would ever be able to be imported. I have never seen a prototype. Supposedly it was roughly 6"x4" in 9mm if I remember correctlly. Anyway, the point being we need 'em in all sizes like the Glocks! Steyr are you listening? Thanks.
