If pocket carry is too much, I would use an In The Waistband (IWB) holster.
A Kahr PM9 was on the borderline for me.
My favorite would be Milt Sparks VM2, EX, or Summer Special 2.
Of course, that means an untucked shirt.
On the good side, I have heard a couple of fashion people say that In is Out, and Out is In.
Maybe they were carrying, and needed to justify an untucked shirt.
