From what I have seen, loops like that are normally staked from the back. I know for sure that the P.38 and Nambu T14 loops are done like that, and I would say the Luger loops are staked as well. If the holes in a Luger are visible from behind, they are more than likely staked as this makes it much stronger. Knowing how anal the Germans were, I'm guessing that they staked it and then ground it flush on the inside. It could also be that they were swaged, which would leave a neater surface that would be easy to hide by grinding it a bit.
Of course: A press fit is possible, but may not be very practical on a small part made of wire. I'm not sure if I would trust that arrangement either, considering what the loop was intended for.
