I pocket carry, and only pocket carry, the airweight J frames. Mika holster. Like others, I have more expensive holsters, but none better than the simple, affordable Mika. Round cut for pants, square cut for coat pockets. For pocket carry, you need only an "envelope" to protect the trigger and to allow an easy draw and to offer reasonable breakup of the outline of the piece in the pocket. You don't need the more expensive. form fitted, boned and highly retentive holster where such design features are more essential in belt carry.
When I can wear a concealing garment, I prefer something much heavier and larger worn on the belt where size and weight becomes less of a consideration.
The J frame is harder for most of us to shoot as well as we might with larger, heavier pieces. The Airweight snubbies certainly have their niche, but, for me, its pocket carry.
