The P comes with some extras too. Plastic case. Extended mag. Maybe another extra mag. It's also available in an all black version.
I have both, and love them, but to me they're the same gun. Many parts including the entire lower are interchangeable. The CW version was not on the market until the P had been around for years and had proven the design. Now that the CW is available, for most people it makes no sense to spend the extra money for the P.
