You cant go wrong with either one. I own several of each. Rugers are tough guns. So are Smith and Wesson. But a S&W revolver is like a work of art as far as I am concerned. I have an old 586 that has a trigger like nothing else. In single action it is better than my 1911. That is saying a lot. But I have several Rugers that I don't plan on getting rid of either.
Find one that fits your hand. Then shoot the crap out of it. You will be happy either way.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
