I have three original Bisley Vaqueros that I use for CAS. Like all CAS guns, between practice and matches they get a lot of rounds put through them, they're in and out of the leather a lot, and they take a beating otherwise, often getting good and wet for extended periods. I don't take any great pains with them, just normal cleaning and oiling, and the faux case-hardening is holding up fine - no rust or unusual wear. It may not be real, but the case-hardening on my Uberti 1873 is, and there's really not all that much difference (which may say more about Uberti than it does about Ruger, but who cares anyway). YMMV, but that's been my experience.
