17fersur:
Welcome to the Forum, and congratulations on acquiring your R9.
The blue CF grips were the first, followed by the blacks. Due to current demand for carbon fiber in the defense and aircraft industries, availability of the product for small manufacturers has declined and prices have escalated. The R9s now being produced carry G10 grips, a material which has its own legion of advocates.
A lot of R9/R9s owners report good results with 124-grain Gold Dots. My own R9s, which is one of the early ones produced in 2004, has digested without complaint the 115 and 124-grain GDs, the Winchester "White Box" FMJ, and the 147-grain Remington Golden Sabers. Right now, it's loaded with the GS "heavy weights."
Continued good luck with your new "pup," and keep us informed.
