Is this legal?
In LA as long as you are 17+, you can OC.
I carry a Ruger SR9c IWB in a White Hat holster.
I also carry a Kahr CM9 IWB in a Tagua holster and occasionally in a coat pocket in a pocket holster if I'm making a quick stop. If I plan to be out for longer than say, 10 minutes or so, I prefer IWB carry.
