At the spring Reno show there was a Hollywood prop blank firing Luger for sale.
It was originally a 1918 DWM taken into Police service. The frame rails under the toggle ears were drilled for a couple of very small pins, which stood just far enough above the rail to keep the toggle from locking, although the breech was fully closed. The barrel had a constrictor ring added to it.
The gun fired special blanks, full-length cases whch were charged and primered and the mouths crimped to emulate a bullet ogive. It is loaded cartridge length, functions in the magazine and chambers automatically. The constrictor provides enough back pressure to operate the now-unlocked-breech mechanism, to eject the empty case and chamber a new one.
The seller had a couple of blanks to go with it, and was including the name of the person who manufactured the custom blanks.
I'd -really- hate to chamber a live round by accident.
