Hello Dave,
Here are a couple of jpegs of the Ideal holster rig for a luger. I believe they were just USA aftermarket items that could be installed by simple grip replacements...no tooling/modifications required.
The grips should consist of a pair of metal spacers/inserts and then a pair of the smooth finished wood grips. The attachments on the holster/stock rig attached to the metal inserts on the grips.
