I got my R9s last Friday and finally got to shoot it yesterday, Monday. I tried three different kinds of ammo, Winchester White Box 115 fmj, Winchester 115 jhp, and Speer 115 Gold Dot. I couldn't make the gun mess up no matter how I shot it. I have rather small hands and wrists, and it was painful on the wrists shooting with one hand. The gun shot to point of aim and grouped well. You couldn't ask any more of a small self defense gun. The only problems I had was in take-down and re-assembly. I bought one of the brass 1/16" punches from Brownell's, but it didn't work well for me. The pin in my R9s is in so tight, I had to use a plastic hammer and the punch to get it out. I held the gun in place and has my wife use the hammer. Once the pin was out the rest of the take-down was simple. Getting the gun back together was another problem. It took many tries to get the guide rod just right to get the slide back on. Once that was done, I had to hold the gun with the pin holes lined up, while my wife hammered the pin back into place. I am not looking foward to having to clean this gun again, which may limit target practice with it.
