I've been carrying a 642 for the past couple of years and it is easy to just put in my pocket when heading out. It's an easy "always along for the ride" gun. But... I just bought a Model 66 3" and I plan to "try" to make that my EDC gun and maybe carry the 642 in the pocket as a backup. I'm going to whip up a belt holster for the 3" 66 and see how well it will conceal for me.

For deep pocket concealment... I like the 642 and sometimes go as wimpy as the Ruger LCP.
