Thank you all for your responses. Richard and tracker are safely on that limb:
1. Grips are factory CF as provided by the seller, though not original to the gun. I used my allen wrench to loosen right grip and then tighten, applying less torque in doing so.
2. I took off to the range and mailed my warranty card for the Robar model enroute.
3. First things first: The first shot was taken with only one cartridge in battery, magazine removed. My thinking was to diminish issues like FTF, FTE and slide travel. Robar R9 went "boom", slide returned perfectly and trigger did not seize.
4. I racked the slide and shot 3 more rounds, each without incident. Happiness is a warm gun.
5. There isn't really a #5 comment but it is my favorite number so I just decided to use it anyway.
Conclusion: The most important role for my R9 is to carry it. I shoot little in the manner I have described elsewhere. However, it is imperative that the R9 I carry works. The Robar RR model I just obtained is easily the finest Rohrbaugh gun I have owned in the 5 I have purchased. This morning's session was very important to me. If problems ensue in future I will return it to the factory. Alternatively, if shooting is the "cure", I am on my way. Thank you once again for your support.
