Re. Pocket carry.
I'm a little surprised no one has mentioned the Blue Force Gear pocket holsters for J Frames. I've carried a 642 as a duty BUG for years in a support side pocket. Used to use a kydex RCS pocket holster back when they made them and it worked fine but there was no flex for movement and sitting. Once BFG released their pocket holster I made the switch and honestly it's easy to forget it's there after all day carry.
