Welcome! And congratulations on your new R9 - getting a new gun, especially one as nice as a Rohrbaugh, is better than being a kid at Christmas! The smiles just keep coming!
Did you get a sighted model? Do you feel that it has/will live up to the hype we engage in here? I've had mine nearly one year now and I actually find that I appreciate it more and more. It seems easier and more instinctive to shoot with every range session.
Again, welcome - we look forward to your thoughts and experiences.
