I think I'm rather unconventional in very much liking a compact K-Frame double action revolver (particularly those with fixed sights) for concealed carry. There are huge numbers of handguns that carry more easily and conceal better but, when choosing a concealed carry handgun, you are engaging in a balancing act between those factors and shootability.

The shootability, for me, of an FBI-configured K-Frame, takes up any slack left by the superiority of other choices strictly with regard to comfort in carry and concealability. But choosing one's preferred point along that continuum is a completely personal decision.
