I got to the range today for the first time.  I warmed up a bit with my Glock 357 Sig and got a nice tight grouping at 7yds.  Then I switched to the R9S, and was all over the place for the first couple clips.  Mainly due to the much longer trigger pull, I think.  Once I got used to it, I was about as accurate as with the Glock.  Definitely more recoil kick from the R9s.
I shot Gold Dot 147gr GDHP, Winchester 115gr JHP (not the Silvertips), and Remington 115gr JHP.  Everything fed, fired, and ejected 100%.  
So I'm just as pleased as can be.  I'll clean it up and lube it, then carry it until next summer when I'll practice with it a bit again.
