I have owned an R9 for many years, and it functions as it should. I shoot and carry Speer Gold Dots which have never malfunctioned and group consistently. I am interested in the new frangible ammo from both Magsafe and Extreme Shock, but at $2 a copy, I would like to know if anyone has any experience with it in the Rohrbuagh before I buy some. Has anyone run multiple clips through an R9 with any of this ammo and, if so, what are the results? Thanks.
