re: Ruger vs SW 357 double action revolvers...

The primary difference is the triggers. Try to dry fire both in double action if you have the opportunity. Some people have no preference, while others will prefer one over the other. Revolvers are expensive these days. That being the case, you may as well consider the Colts too if going up a price level isn't prohibitive. And last, there is nothing new under the sun -- the only common revolvers worth having are Smiths, Rugers, and Colts.
