Hey, you're carrying concealed. Who is gonna know?
I think of the LCR as modern-looking or even a bit futuristic, form following function to a high degree. I don't object to its appearance, but the lines of the Smith echo a look we've had a century to get used to. One is modern, one is classic--both are very good revolvers.
No big deal. The S&W 638 is more humpbacked than the LCR and people pocket carry that with no problems.
The LCR or the 642 will do fine for pocket carry. I find that pleated-front canvas pants (Dockers and the like) do a good job of making a small revolver in a pocket holster disappear.
