DeSantis Nemnesis pocket holster...
If you want deep concealment & to have quick access to a J frame snub revolver, I'd buy a DeSantis Nemnesis pocket holster. The sticky fabric design works well and you can remove-add the firearm with ease if you go into offices or places that restrict weapons. The Blackhawk CQC holster comes with a paddle attachment too.
I'm not a big fan of paddle styles but they may work better than other holsters.
