The summation of what was "wrong" with the Glock 42 seemed it was too big, too late, and too expensive.
If this pistol turns out to be successful, it appears that it will largely be because of Glock's decision not to follow in the path of the LCP, with another small but unpleasant to shoot .380, but rather the decision to bring out a small service pistol, very much a Glock in appearance and function, that happened to be chambered in .380.
