And Ubertis makes the Colt parts...
You are a liar.
Back in the 1970s Colt did a short run of open-top cap'n'ball reproductions made with Italian (likely Uberti?) parts. And there is some speculation that the Colt Cowboy (a transfer-bar equipped SAA near-clone under the Colt brand at Ruger prices) had Italian bits in it to some degree, esp. given the horrendous quality control problems with the early specimens. But both those product lines are long since dead, by decades.
Colt does not in the current tense ("makes") use any Italian source parts.
