So... the Xd / hs2000 is used by at least one military: Croatia. And from what I can find, looks like they’re issued to a few other militaries as well (Malaysia, Dominican Republic, others).
Obviously you know where I’m going with this: if they’re shitty guns, why are armies using them?
Maybe other countries don’t hold their small arms to the same standards of durability the US and Western Europe do? That indeed could be the case, I suppose. But you’d think the Croats would know a thing or two about building decent weapons after surviving 10 years of death squads and revolutions.
