I like the color case-hardened finish on one of my Henry Big Boy lever actions and was thinking of picking up a Vaquero with a color case-hardened cylinder frame. I've read some comments that Ruger did not execute that very well and some owners were not pleased with the longevity with the finish. Was this mostly on their original Vaqueros only or also on their New Vaqueros? If there was a problem, does it remain a problem if the owners keeps it covered with a layer of oil when not in use (like any blued gun should be)? Also, is there a reason why the barrel and grip frames are not done in the same finish, or was it done to just tip the hat to an "old west" style in appearance. I would like to get a New Vaquero birdshead 357Mag in all-blued, but it seems Ruger does not offer that (or at least I've never seen one for sale on GB). Thanks in advance for any comments!
