My complaint with Nill is that they are using heavly grained walnut with dark, almost black, vertical stripes.

When I look at most authentic, original Luger grips they seem to be fairly uniformly colored. And, Nill prices aren't very attractive. Sure seems there is an opportunity for a quality manufacturer to make a profit by selling accurate grips made of a variety of woods (as G.T. does mag bottoms), and at a reasonable price.
