Thanks everyone for the replies. @Alaskan454 and @IHAVEGAS- your detailed information is very much appreciated.
After a phone call with Ruger and a conversation with a local smith, I decided to send it back to Ruger. Process was painless and free, and I got the revolver back within 8 days.
The invoice states they did a pawl adjustment, and it works like a dream. After another field strip, I could see the change, and, interestingly enough, it is much easier to get the trigger assembly back into the frame as well (a symptom of the problem no doubt).
I plan to put enough rounds through this thing to break it one day so I will post an update if I do anything remarkable.
Thanks again!
