Dwight,
If you prevent the toggles from going down far enough to lock you are half way to having a blowback. The remaining question is feeding the cartridges. The Luger is meant to be recoil operated and the barrel/receiver moves back a bit before picking up the next round from the magazine. I'm not sure how that would work. Firing a blank with a muzzle restrictor doesn't produce any appreciable recoil. Guess all this fits under the category of "modified recoil action".
