That 44 mag original Vaquero is awfully nice. I've often thought of sending mine in for real color case hardening. But when I rethink it, I toy with keeping it original and have one of my New Vaquero 44 specials color case hardened because I want to shoot it, and the New Vaqueros have Ruger;s RIPS design which lines up the chambers with the loading gate like the old model Rugers, which is much more convenient for loading and unloading.
I'm also working on making an Old Model 3 screw w/o transfer bar from one of my mid frame 44 specials. I've completed my tool room mock up on a 22 single six new model discarded frame. Just need to decide to do a Vaquero or a Flattop Blackhawk.
