Back when I was regularly pocket carrying j-frames, I tried a bunch of pocket holsters. Leather, Kydex, various fabric-based ones, etc. The only ones I found that worked well for me were the Uncle Mikes and Desantis Nemesis. I preferred a holster that conformed to me and the gun and flexed around movement. The Uncle Mikes were cheaper and available at places like Walmart if you needed a quick replacement.
