6" stainless Colt Python. Satin because I couldn't find an Ultimate. Smitten by this "apogee of American gunsmithing" in all the glossy magazines and books, I ended up with something that would bind after a couple of cylinderfuls of hollow based wadcutters and I found it difficult to clean the cylinder that needed cleaning every 15-20. Traded it in part exchange for a tuned Smith 686 with adjustable foresight which worked like the Colt should have...then they banned handguns...
