My wife has carried the 3" for 13 years. Great little gun. When she took her tactical training course, she outscored everyone in her class, including the men with their automatics. I have one in .22, and it's really fun. Super strong design (of course, it's a Ruger).
As far as DA revolvers go, I'm a S&W guy, but the Ruger is the best small, 5-shot revolver on the market.
