For pocket carry, LCP, I have the LC9S and it is my daily OWB carry, if I need to put one in a pocket, it is the LCP - I call it my church gun.
I also have the P238, and it is a great little pistol, but heavier than the LCP, and because it is the "army" version, the bigger grip makes it more obvious in a pocket. But it is a sweet shooter, and my wife has the rosewood grips and hers is more pocketable.
The LCP disappears in my jeans pocket with a sticky holster, I did add a hogue handall grip, steel guide rod and a heavier spring in my LCP which helped with the snappy recoil in this light little pistol. Also the ARX 56 grain ammo cycles through it fine and also helps with reducing recoil. With 6 rounds and a bit of practice you can do 2 in the chest and 1 in the head twice without issue.
YMMV
