I taking it you have 2 different questions...CCW and fast draw with different handguns(?).
(1) This is for
CCW, huh? Full Size Vaquero?
My choice would be a 3.75" or 4.68" Bisley Vaquero modified to birdhead rounded butt and checkered panels, but keep the Bisley hammer and trigger. Heck, I'm just guessing here. I have a different CCW handgun than Ruger six-guns. The Rugers are more for open carry to me.
(2) For
fast draw competion? I don't know. I never really cared much for it.
But I reckon a 4.68" standard (plowhandle) Vaquero with checkered grip panels. I guess I'd say stay with standard trigger and hammer (tall).
Your mileage may vary.
