An Airweight J frame is very, very hard to top for a pocket gun. Either a hammerless, such as the 442/642 or a Bodyguard, shrouded hammer version.
I carry one as a second gun every day at work and talk to a lot of turds with my in my pocket, all casual like, until I determine if they are a potential threat or not...
My 442 is one of my 5 "must have", basic handgun battery guns.
