I have options in three of the classes.
Pocket 380, Ruger LCP, a true "pocet pistol" The gun you can carry when you can't carry a gun!
Pocket 9MM, KAHR CM9. Pocket carry in a DeSantis Nemesis, same as Elsie. But also, and more often carried IWB in a Theis holster.
Pocket snubbie, and my latest purchase, Ruger LCR 38 Spcl +P. Surprisingly concealible in a DeSantis Nemesis pocket holster.
Interestingly, all three of these 100% reliable, and accurate pocketable handguns cost less total than one Rohrbaugh R9
I haven't tried pocket carry with my Springfield XD40 Sub Compact. Seems too wide, and heavy when fully loaded for that type of carry.
