Try KSD grips.
Might not be much darker. I might have a pair of wood grips. If I don’t mention it in a couple days, send me a message.
I was going to order a grips, but I'll hold off in case you (or anyone else reading this) has a pair I like for sale.
Thanks for mentioning it.
I'd rather buy off a friend than online anyway.
I looked up the KSD grips: thanks for the tip!
Both are $90 each, I found.
Not sure if I like the darker over the medium color since the medium has some darker mixed in.
Further down from these pics is a pic from Gunbroker: $60.
Sorry about the fuzzy pic.
