Well Hugh, I bought some off of e-bay and then spent a lot of time getting them adjusted.
On the 1st picture, the safety would catch until I relieved the wood in the two red areas.
And then on the other picture, I had to relieve the wood or the magazine would slide out, since it was pushed in by the grip!

Very frustrating, so buying them from Hugh doesn't seem like a bad idea, grips for a Luger are much harder to adjust than .45 grips, which are just slabs of wood. (I've made several in zebra wood, very pretty).
Hugh what does the Cocobolo grips look like smooth?
