Cannot clarify but can concur as to G10. I hate G10 and wish grips were available in Micarta. Factory claims they considered Micarta but nixed it. My guess it was a cost factor.
Micarta polishes to texture of amber while G10 stands in the corner and sucks out loud. While I concede G10's dielectric properties, for industrial application, it is caustic, (in my view), for so pretty a gun as the R9.
I will settle for aluminum to get rid of G10 but wish there were better choices available.
