I think they'll eventually come out with a single stack 9mm, but don't think there's anyway it'll be the size of the G42. Lots of guys bad-mouthing the G42 on the 'net because it's "big" for a .380, but IMO, it's great, especially for those who have been training with and carrying Glocks for years. Glock controls, Glock reliabilty, real sights, and disappears easily.
