+1 on the welcome to the forum.
Your gun is okay. You should have a four-page dis-assembly / lube instruction brochure with the paperwork for your Rohrbaugh. If it's missing, go to the Rohrbaugh website
http://www.rohrbaughfirearms.com/, click on the "downloads" tab at the top of the homepage, and download the document. There is a good picture of the trigger linkage system on the last page.
One thing we Rohrbaugh "veterans" have learned is that you must keep after those little grip screws. The right grip is critical for function of the trigger system. A drop of blue Loctite (or clear nail polish will work in a pinch) on each screw is really helpful.
Make sure you use a good-quality hex wrench on the screws.
Keep the screws tight; keep the pistol clean & lubed, and I think you will find your pup a reliable and faithful companion.
I've carried mine on a daily basis for more than five years and wouldn't want to be without it.
