Well...I disassembled my R9 last night to replace the recoil spring as I experienced a few FTF's on WWB.
Once I removed the slide and attempted to remove the recoil spring assembly, the assembly shot out.
Apparently the inner guide rod had broken at the threads from the retaining disk. So...I recovered most of the parts, but the broken inner guide rod is gone. I have the disk, sheared off at the threads, and a bent inner spring.
Sent Rohrbaugh an email...hope they can just sell me a new inner guide rod, spring, and retaining disk.
