dbracin:
I'm glad your problem was resolved by the factory so quickly -- and a six-week turnaround during a month when the factory was closed for several days to give its small staff a breather for the holidays is indeed quick response.
In your post of November 26, 2007, you stated, "I did purchase it new and I don't recall noticing this slide to frame fit. It could have been like this all along or it could have developed it. I will contact Rohrbaugh."
Each R9 is carefully inspected and test fired before leaving the factory. I find it difficult to believe that any piece with as much variance from the norm when in battery as was shown in your initial photograph would not have been noticed and sent back to the line. Since you purchased the piece new and did not notice the problem when you took delivery, I am still inclined to think that some aftermarket damage must have occurred unbeknownst to you which threw the slide out of specifications and interfered with the slide/frame interface. The amazing thing is that the pistol apparently continued to function -- another tribute to how tough these little masterpieces really are!
Whatever the cause of the problem, the factory has (as usual) made it right. I trust that you will have no more problems with what (IMNSHO) I consider to be the finest pocket pistol yet produced.
Best wishes for the New Year!
