I have a pocket holster for my J frames (I think it is a DeSantis, but I am too lazy to look); I don't carry a J frame often and almost always only as a BUG. I use a Kramer Leather pocket holster for my G33, and a G26 before that. Works great. I also have a Mika pocket holster for my 296. It works with a big enough pocket, but I'm pretty good sized and it only works in my 24-7 cargo pants.
Pocket carry is very good for many purposes. I have often carried in places where legal, but where discretion is critical. In dress clothes, I can take off my coat and look unarmed. It is not good for a draw when seated if the pocket is in your trousers, but there are compromises that have to be made. It is a sound choice for ME - no guarantees it will work for you. I carried a J frame a long time ago without a holster, in pockets I had to beef up with pants patches. The cylinder still cut through the cloth pretty quickly. Use the holster, one that keep the trigger covered. There is no down side if you use a quality piece of equipment designed to stay in the pocket when you draw.
