Took the R9s out today and shot 30 rounds of Speer GD 115gr, and some WW 115gr round nose, not one problem. The Pachmayr number 4 grip works beautiful on it. My wife even shot couple of mags through it. She did have one ftf. Got to hold that little canon tight, but such a sweet gun and so well made, thank you Mr. and Mr. Rohrbaugh!! No levers or extra buttons to full with just pull 'er out and start shoot'n. Also shot the P9, PM9, and the P32s. No problems from any of them except the P32s key hole a lot. The PM9 Black Diamond has a number 4 grip on it also, very good! Those of you that may be looking for something just a little bigger, don't pass up looking at the PM9. SOOO sweet, even shoots better than the full size P9. Very good trigger and windage is perfect on it, just a tad high.
