The LCR is a good choice. It is not too big, it is more powerful, easier to grip and aim, and can be quick as lightening out of a holster on the hip.
Yes the pocket gun will have it's place, but only as a last resort when it is Impossible to carry anything but. However, later become fully armed. It is not difficult. A little snub nosed revolver can fit in a ton of different holsters made for concealment.
Look for opportunities, they are everywhere.
