I haven't welcomed you aboard, bnightrider so "Welcome to the forum!"
IMHO, you can't go wrong in stripping, cleaning, and lubricating your new R9 before your first trip to the range. That way, if you do have any issues, you have already eliminated the 'was it clean / was it lubed' questions from your troubleshooting list.
That said, the first couple of times you take down an R9, you'll probably have sore fingers and well-exercised cuss word muscles.
With four years of R9 experience, and a couple of home-made tools, I can break down and reassemble my pup in a few seconds.
Make sure you read the threads and FAQs on field stripping and types of lubes to use.
Wishing you "Good shootin' " at your first range session,
Steve
