You may not be looking for revolvers, but I have the Ruger SP101 and it works for concealed carry very well. My wife can shoot it with .38 special and I can shoot .357 Magnum if I choose. She's not interested in CCW, but she is home alone sometimes while I'm traveling. There's a lot of flexibility in the SP101.
For pistols, I'd check out the S&W M&P 9mm Compact.
