Haven't shot the LCP but do have a pair of LC9s pro's.
Apples and oranges. I love my LC9S pro, and can shoot it all day without discomfort. Not so the LCP. As the other poster said, it's like a firecracker going off in your hand on each shot. Go with the Glock 42. So much superior as a shooter, and still would work as a front pants pocket gun, if that's required.
