Since you are wearing a jacket a pancake style possibly a DeSantis JIT. You may be able to find a Bianchi 9R for the 2 1/2 K frame. It is kind of heavy but I wear mine like that frequently and it works well. The advantage of the Bianchi is it is fairly easy to get to with your left hand. 2 guns so you can get to something with either hand could be important. Standing talking to someone with your hand in your pocket appears relaxed. Holding the grip of a small revolver as you are talking is a big advantage. ymmv
