I bought the Farmingdale, in March, 2005, from a forum member who knew me from the custom knife world. It was his spare R9. Maybe he preferred the two tone? Now I feel even worse if the one tone I had was so rare.
When I bought my second R9, in 2008, I was bummed by the G10 replacement grips and did not like the two tone gun as much as the one tone.
Ultimately, Yankee 2500 became my "accidental R9 guru" when he wrote in this forum about the (aftermarket) Robar model he had ordered. I found one in the forum classified hours after being posted and have never looked back.
Then Yankee found the Rafter S holster and I ordered the same one. The only R9 matter in which we differ is the mag extension.
