KorrMuraan:
First, permit me to welcome to the Forum.
With its weight of 12.8 ounces and tight tolerances, the R9 is not designed to accommodate +P or +P+ ammunition. The owners handbook provides the following advice in that regard:
"CAUTION: USE ONLY ORIGINAL HIGH QUALITY FACTORY MANUFACTURED (NO RELOADED) 9mm STANDARD PRESSURE PARABELLUM AMMUNITION IN GOOD CONDITION. DO NOT USE +P OR +P+ AMMUNITION. Your Rohrbaugh Pistol has a short barrel to minimize overall size. +P or +P+ ammunition will not result in increased performance but can cause undue wear and failure of the mechanism."
Different owners of R9 pistols have settled on different brands and loads as their carry ammunition. I've heard that Karl Rohrbaugh carries Winchester Silvertips in his own R9. A lot of owners have chosen Speer Gold Dots in standard-pressure 115 or 124 grain loads. I personally use either the Gold Dots or the "heavy weight" 147 grain Remington Golden Sabers in mine. For practice at the range, Winchester "White Box" FMJ is a common choice.
If you are intent on carrying a 9mm with +P or +P+ ammo, you will not want one of the R9s. However, if you want to carry what I consider to be the smallest, lightest, most concealable, and highest quality 9mm semi-automatic handgun yet made, the R9 may be your answer.
For further information, you could check out some of the ballistic data contained on Chris' FAQ sheet, which has a rotating link at the top of the Forum's opening page.
Good luck, and welcome again.
