No one has been more vocal than me as to approbation of Carbon Fiber and dislike of G10 grips.
Two things: First, factory should take the picture of CF grip Stealth off their website. I am not their spokesman but there is no way they are not aware that CF grips are coveted and G10 is either openly disliked, (by those like myself), or generally regarded as lesser value than CF.
Second, I concur with FB as to Hogue grips. If you have to be G10, you might as well look decent. Given the cost of the R9, I think Hogue grips should be stock.
