Greetings everyone, I'm looking into purchasing a Ruger single action revolver, and cannot decide which one to purchase. Is there any difference in the frame strength of the current production new Blackhawks or Vaqueros? I’ve heard that the Blackhawks may be able to handle higher pressure loads than the Vaqueros? Is this correct? Another question I have is, are the grip frames and trigger guards made of steel or aluminum? I’ve heard that on the stainless guns, the grip frame and trigger guard is stainless steel, whereas on the blued guns the grip frame is aluminum. Could anyone verify this?Also are stainless guns weaker than blued? Thanks!
