I bought a 60-4 (.38 spl.) about a decade ago. The 3"/heavy barrel configuration makes it seem like a bigger gun in the hand, but it hides very easily. I liked it so much I recently found a LNIB 36-1 (again, 3"/heavy barrel, only in blue) for my wife. Even +P stuff feels mild with the extra mass. J frames are certainly easier to hide well and I don't think I give up much on "shootability" with 3"/heavy barrel guns.
