The pocketability issue is new and interesting. It's also likely very clothing specific. I own a pair of shortstop would allow me to pocket a 5" barrel 1911, so I see how it could be viable with the right pair of pants. But this is a situation where you'd have to dress around the gun.
As far as the 43X itself, for whatever use you'd have for it, there seems to be a better alternative. If that size gun fits the bill, I'd rather have the Springfield Hellcat Pro. Its as close to exactly the same size gun as two guns that weren't intentional clones of each other are going to be. It comes with factory 15 round mags (and they have a promotion where a buyer can get 5 of them included.) It has better iron sights, and is natively optics ready. And, it's cheaper than the 43X MOS, and much cheaper if you factor in the cost of a few S15 mags and the metal mag catch.
Another alternative if you want a compact 10 round mag 9mm is, of course, the P365. That gun has been done to death, so I don't need to compare features.
Sorry, I just don't see where the 43X had any advantage that makes it worth buying.
