MY USFA is a Single Action, .44 Special, 4 3/4" all dome blue (no casehardening) Model listed on box is "SA"The serial number is 28657. Grips are black checkered hard rubber. Total cost was $872.81 out the door.
I ordered the gun in 2009, but didn't receive it until August 24, 2011. The gun was ordered through a local gun shop initially as a Rodeo II. I had to pay an additional $100 "special order" charge because .44 Spl. was not a listed caliber - only .45 Colt and .38 Spl were available for Rodeo II's. Then USFA discontinued nickel plating after a long delay, and ran out of .44 barrels. Finally my gun store called me to say that USFA was ready to ship my 5 1/2' CCH and I said "Wrong gun!" Finally Gary Grainger called me and we settled on the all blued 4 3/4" .44 Spl. Single Action, probably in June of 2011. He said he would add a .44-40 cylinder to compensate me for the wait. That didn't happen, and the gun arrived at my LGS 2 months later, in August 2011.
I hope this information is helpful.
