The current Blackhawk Convertibles only come in blued and they do have an aluminum alloy grip frame. Generally, they have only been catalogued in blue but I believe that in the past there have been some limited distributor runs of stainless convertibles. I know there were some distributor runs of both blued and stainless .45 convertible Vaqueros (not the New Vaqueros) which had steel grip frames. I had one quite a few years ago and was a bit suspicious of the aluminum frames but I currently have a couple of the newer ones and have become a big fan of the alloy grip frame - at least for standard level .45 Colt and .45 acp. I think they are the perfect balance of weight and handling, at least at that power level. Mine have become my favorite revolvers., even above my GP. I consider my P90 to be supplemental to my Blackhawks, LOL.
