I received my R9s, No. 196, yesterday, and had a brief trial today. With WWB 115 gr JHP, 42 rounds, had no problems. With Speer GD HP 124 gr, had two FTF out of 14 rounds. It may have been the same round failing twice since I ejected the failure and put it in the next magazine.
Accuracy was scattered, but that was more me than the gun. The DAO long pull is very different for me. But, I was able to settle in more toward the end.
It's a great feeling little gun.
