Well today I am the proud owner of a stainless steel Ruger Blackhawk in .357 magnum with a 4 5/8" barrel. I had considered buying the 45 caliber model, but I just like the .357 ( I own six .357 mags already) and I'm going to start reloading .357/38 in the next couple of months. I just felt like it made more sense to get one in .357. I also decided to spend the few extra dollars for stainless steel. I'm happy. I've heard many good things about the Blackhawk over the years so I'm confident I won't be disappointed. I know that my GP100 has grown on me.
