I had originally puchased a Desanti's Nemesis and returned it the next day.
After a bit of research, I stumbled upon
Mika's Pocket Holster's
I purchased one of his pocket holsters for my S&W 638. I'm extremely pleased with it. Very easy to draw from and re-holster. The holster stays in the pocket as it should and does an effective job of holding the gun in one position in the pocket.
It took roughly 5-6 weeks for the holster to arrive. This might seem too long to wait for a $20 holster, but I'm glad I did. I realize that some of these smaller holster maker's have other jobs (as Robert does), so I'm willing to cut them a bit of slack when it comes to the wait. He was very quick to point out that it would take a while before I would receive my holster due to his backlog and schedule. Well worth it in my opinion.
Anyway, here's some pics:
