I've not thought through the actual implications of that, but they are indicating it works great and is a nice source of inexpensive plinking ammo. But I'd not try it without researching more. Extractor holds the round in place even as it's firing even though it's not headspaced on the mouth. Once fired, the pressure keeps it back against the slide face.
You could always get a .40 barrel for it. Then it would be as simple as a quick barrel swap and you'd not have to worry about the headspace issue. It might not feed quite as reliably due to the short round in a long mag, but should be fine for cheaper practice, I would think.
