If you don't mind, can I ask if you shoot the Vaquero or the New Vaquero?
I shoot the New Vaquero. Mine is the stainless 5 1/2" model, but the finish and barrel length really are more of a personal preference than anything. The only drawback to the newer models is a lack of custom grips for them, most custom grip makers are just now making grips that fit the new models. I wanted aged ivory on mine, and nobody was making them for the New models yet. I did a lot of modification work on a Ajax set for an Old Vaquero, and finally got them to fit.
Guess what happened two months later? Yep, they came out with the grips I originally needed for my pistol!
I don't disagree with anything Deadeye Don wrote, but I will throw this in, that I've heard of a lot of "tinkering" that needs to be done with a lot of Colt clones. All I hear from people who shoot Vaqueros is that you only need to pump some lead through them to break them in, and nothing else. Mine (which came direct, new from the store) felt like they were pretty much already broken in when I first pulled the trigger. Lots of folks will call any Ruger a good "starting" pistol, suggesting only greenhorns use them. What bunk. I know plenty of serious competitive SASS shooters, many of them shoot with Vaqueros! Don't let the "You're nothing unless you have the most expensive toys" types talk you out of a darned fine pistol. They look good, cost about the same as any other Colt clone, they're built like a tank, and require very little gunsmithing. Oh, they shoot great as well. If you were a Western re-enactor or making a movie, I'd steer you away from a Ruger. But if you're shooting CAS, I'd recommend one wholeheartedly!
