These two catalog (or magazine) photos purport to show the upcoming Glock 42. I think they look legit. The specifications are almost exactly what I predicated they would be, not because I am some sort of gun seer, but because it they simply make the most sense.
The specifications are for a .380 ACP pistol with 6+1 capacity, white-dot notch sights, a 5.5lbs trigger pull and a overall weight of 13.4 oz empty.
I predict they will sell truckloads of this pistol.
