I love my S&W M57s. Kcub, you still looking for that 44 mag? I consider my 8 3/8" M57 the finest revolver I own and I have owned many and continue to own quite a few. And yes, I like it better than the couple Pythons I have owned. Frankly, my Trooper Mark III is my favorite 357.
Colt Snakes? Got more than a couple. Great guns, but Smiths are pretty good too especially the M17, M18, M19, M27, M29, and M57's.
I sold off a 5.5" Ruger Redhawk in 41 mag recently and I keep thinking... maybe I should have kept it. I seldom have any remorse when I sell a gun, but this one was hard to find in the first place.
