Capt'n,
The cylinder flutes, the fit of the loading gate to the frame, the Colt like up-sweep of the hammer and the vertical rear of the front sight all indicate "US Made" to me. Another more subtle indication for me is the shape and contour of the back strap and trigger guard. Every Italian replica I've handled (not that many) and the USFA gun that I had, made from Italian parts, all feel different in the hand than the 1st Gen Colts I used to own and shoot. The all US made USFA guns have the same feel in the hand as the 1st Gen Colt, as does this Rodeo.
That's my story and I'm stickin' to it. (smile)
