I definitely hear you on the "depends on the pants" bit.

I have pocket carried a 657 UDR many times and been ok with it, but it takes a stiff pair of pants with deep pockets, something like the duluth cargos.

These polyester rip-stop 5.11s I have to wear have decent pockets, but are so flimsy I'm afraid everything is gonna show, not just the gun. =P
