First, I'll say that I've found that bulk in the pocket is going to occur regardless, really. You'll end up chasing the ultimate holster trying to save half a millimeter of thickness. I have a box of pocket holsters to prove it.

I have not had a Nemesis for a J frame (had a Keltec P3AT one) but have had a Mika round cut for a J frame. Good holster made by a good man. I used it with jeans or coat pocket carry.
For pocket carry I'm currently using a Tuff Products Pocket Roo with a Safarliand Comp I in the speed strip pocket. Reload and gun together.
