While the R9 comes well-prepared, I will not fire a weapon that I have not broken down, inspected, and lubed. I have seen them come in dry, and come in dripping.
They are not that big a deal. Scary the first time, though. The hardest part is getting them started, and a CAREFUL use of a thin knife blade works. I then use two hemostats to grip the two pins so they do not come out with the grip panel. I pry the grips up off of the hemos. They are set in pretty tight. The two pins are a pain to replace the first time.
I will remove the grips and clean/lube twice a year.
