As was said above, the .380 guns are exactly the same size as the 9mm guns, with exactly the same magazine capacity, so what would be the point? A much poorer performing round in a gun that is the same size and magazine capacity, not to mention much more expensive ammo? Not going to happen, I don't think. About the only selling point would be if someone wanted one to complete a collection, but I imagine demand would be so low that Glock wouldn't ever even think about producing them here for that. IIRC, I seem to remember being told by the instructor at an armorer's class, when someone asked about the .380 guns, that they were primarily produced for sale in countries where 9mm or larger calibers were forbidden for civilian ownership. I could be wrong about that, but that's what I seem to remember, anyway.
