Have you considered any Kahr products?
For comparison I have copied and pasted the specs of the LC9, the PM9 and the PM40.
I own the PM40 and it is a fine value. It has a nice trigger action, although I really prefer a shorter pull. But as a compromise of size, reliability and power I find it excellent.
Thinness is a major factor in concealability of a handgun. The LC9, of these three, is the thinnest; but it also has the greatest height and length.
