S&W 686 (or 686P if you want a 7-shot cylinder). Stainless steel, 2.5" bbl., hogue rubber grips. Kind to the hands, even w/ hot .357 mag loads, mainly due to the weight (about 32 oz.), but the grips are good, too.
I have the 7-shooter, & I just carried it in my fanny pack while walking around Greenlake (4 mi.) this A.M. w/ the fiance & our collie. I wouldn't necessarily go jogging or running w/ it, but it isn't uncomfortable either. BG's are sure to be intimidated by it's appropriately powerful appearance.
Another good choice would be the S&W Lady Smith, which has 5-shot capacity & a unique 3" bbl.. This is really a nice gun. I almost got it, but could only afford 1 revolver & wanted to have the higher 7-shot capacity, which I tend to favor because of the contemporary
verbotten frutzen status of hi-cap anything. But, the LS is a really nice gun. Originally envisioned as a female-friendly CCW gun, it is probably a better choice for CC in general than even my 686 series.
