You can order them from Altamont, just like you can order Hogue Grips directly from them, although they like Hogue may have distributors, you would have to check out at their site.
I have some Altamont grips. The fitment is a bit off, and there’s a slight gap on the right side grip panel. I tried to like them and ultimately took them off. The color is close to what you’re looking for though.
I second Brian on bestpistolgrips.com
Here are a few sets...
This is the set I got for my MK25 perfect fit, quality work.

I agree as I have seen grips images of actual "rosewood" grips that vary drastically in color.The biggest "problem" with hardwood grips, regardless of manufacture, is the coloration the grips will take. Each blank can take on a different hue, dependent on graining, and the batch of stain and filler used, itself. That's why most grips pairs are cut from the same blank, so graining matches more closely.
It's too bad, you can't choose your grips by visually looking at the selection of grips, that are available.
