Luger will not fire until the trigger is pulled twice.

Sounds like the disconnector ( the little plunger at the front of the sear bar) may not be resetting properly until bumped by the trigger bar. Check it to make sure it's clean and lubricated.

Also look at the small axle pin (the fulcrum) that the sear bar rotates around. Make sure it's clean and in position.
