Yes, the Coyote was the only Ceracoat model we ever built. Besides the difficulty of matching the slide and frame color, we found the coating was too thick to use on our R9 due to the already tight tolerances on it. We phased out the Coyote almost immediately after showing it at the S.H.O.T. Show in Las Vegas, NV, which is why they are among the rarest of R9 factory models, which include the R9 Stealth Elite Premium, of which there were only 16 ever built. The serial numbers on the Premium models were different also. Rather than the usual run "R1234", the Premium serial numbers ran as follows: 1 of 16, 2 of 16, 3 of 16, etc. In reference to the "Custom", which had a greenish hue to the slide, that was something I called a Custom due to that feature. We were trying different approaches to colors during a time and that was one which, a supplier we were using for the Stealth's blackened slides, showed us. I decided to make that R9, there were maybe 6 or 7 of those, and sold them as such. . . . . Explaining to the shop owner who purchased them there are just a few of those and that we really will not be making that model. They were "test pieces", if you will. Fun R9 none the less. . . . and yes, also a rare bird in the field of Rohrbaugh designs as the Custom was never a real model, but just that, a Custom put together by me at the shop one day.
