Gunbroker or something similar would probably be your best bet for that. I doubt anyone here has a New R9S considering we are not dealers.
Chief: GunBroker is great to sell, but I find not as good to buy. I've already heard from 2 members here on the Forum. So, we'll see. I decided to form a small collection of R9's to hold onto. I have a new R9S Stealth, a new R9S Stealth Elite, a new R380 Stealth, and a R9S Stealth with minimal use for carry. I plan to buy a R9S next.
