For all heavy handgun loads I prefer the Super Blackhawk grip frame. I set up some .44 Magnum and .45 Colt Rugers years ago and tried them with varying loads. I had 4 5/8" and 7 1/2" guns set up as Blackhawks, Super Blackhawks, and Bisleys. I shot everything from 180 gr. bullets to 350 gr. bullets. After all my shooting was done, my pick was the Super Blackhawk.
