Went back and looked at my old emails. If memory serves, after several "misses" with blind online orders (only to receive grips that didn't fit) I think I ended up with success from these 2 makers:
Dave Corbin / Tombstone Gun Grips
PO Box 2171
White City, OR 97503 USA www.TombstoneGrips.com
I'm going totally off memory, but I think Charles Spresser's grips are the ones I ultimately ended up using, which are still on my Denix today. Hope this helps!
