An issue with the Owen is its cartridge, 9mm. As it happened with the Sten, the British didn't issued these weapons to the Mediterranean based on a logistics problem. They simplified their logistic chain in this theatre by using only one type of SMG cartridge, the .45 ACP.
But if someone is interested in making a landing on Bougainville map, it would be a nice choice for a SMG!
