I got to handle an Original Colt Bisley Single Action Army today. Also, an Uberti copy of the Bisley model, and a Ruger Bisley Blackhawk, all side by side. The Uberti is almost identical to the Colt. The Ruger is larger, and the grips are different. I discovered that I cannot use the original Bisley grip shape. They are too small, and the grip angle is very uncomfortable for me. The Ruger Bisley grip, however, is the cat's pajamas. I understand that not everyone likes it, but I love it. It fits my hand perfectly, and has the extra length I need to keep my little finger from slipping off the bottom. I might have considered buying the actual Colt, anyway. It was a tad out of my price range.
