What makes you think that? They didn't have to do anything to design the 30S, as it was simply a 36 slide on a 30 frame. Creating a 21S will take a substantial investment. And if they were going to do that, I would think they would go 9mm, don't you? I don't see a 21S anytime soon, if at all.
But if they did, yes, I would buy one.
