Yeah, this is in a full-power cartridge, 8×50mm - it would be completely uncontrollable and impractical, hence why it never went past the prototype stage.
However, at this point in time, people were still figuring out the definitions, so the pistol-caliber as a requirement hadn't really set in yet - I assume the designers of this one literally meant "machine gun but small" (hence the sub- prefix)
