I have the whole setup off a gun I sent back to ruger for replacement.
light honest wear, grip locator pin, factory rosewood inserts, screw/ferrules and all.
I originally kept them cause I thought I would be getting a new GP-100, and I didn't want to be stuck with the hogues.
However, I had it replaced with a 5.5" stainless SBH that I put my stainless bisley kit on.
The GP100 grips have been sitting on my kitchen table with all my other "stuff I'll try to sell sometime" for about 2 months.
Make me an offer, or maybe some knowledgeable soul can come along and arbitrate us a good deal for both parties.
