I'm wanting to get a new model Vaquero. I'm having trouble deciding on caliber and finish. I've decided on the 5.5" barrel length. I do intend to shoot it but not everyday and I'm not going to be competing. Stainless would be easier to clean but the blue looks so good. Do the blue Vaqueros come color case hardened? As far as caliber, it would make more sense for me to go with .357 over .45LC because I have several other revolvers that fire .357 and nothing that shoots .45LC. Any suggestions? I would greatly appreciate some advice.
