I am very sorry to hear of your problems of late..
What has changed since the previous good results?
The big brown truck just left and I got to try out the R9s. FOUR mags of Remington , 2 mags of WWB and 2 mags of Federal Hydrashock. No problems. I feel much better now. I wanted to shoot more, but after 8 mags, I thought I'd wait until tomorrow for a few more rounds. Let me say that Rohrbaugh customer service is excellent. Maria is an asset to the company and Karl has a sense of humor. My letter with the return indicated light strikes with Remington, Winchester and CCI ammo. Included with my returned R9s was a handful of "Federal" cases, I concluded were test fired cases. Well, so far so good.
If this was a good run,we must realize that something has changed..
