the theory is that Glock doesn't care to import them. It would be easy for them to make them legal to import but there is no reason to. They have the exact same dimensions as the 9mm models so there is no benefit to making a gun in a weaker, more expensive cartridge. The .380 models were made for places that have strict gun laws that prohibit their citizens from owning certain calibers.
Glock doesn't want to cut into the sale of the 9mm models by offering the .380 in free countries like the US.
