I just bought an R-9S so I thought it would be a good time to join this forum which I've enjoyed reading for awhile now.
I haven't shot it yet (waiting for some Super-lube) so I have little to report except that it feels great.
I've noticed in other posts that some people are waiting a long time for delivery. I bought mine from Forrest and Field in Norwalk CT (promised delivery in a week and delivered in 5 days) and I know they have another in stock at least as of yesterday. A very good place to deal with.
I'll let you all know how it shoots and thanks for all the technical advice I've gotten here already.
