Go with the PPS, easy to use, small for CCW, better sights than PPK and 9mm which is less expensive than .32 or .380auto and more "stopping power"(if you believe in such a phrase), 3 choices of mag capacity. Its very slim and snag free compared to the PPK. The only downside is its DAO mechanism. If they could make a PPS with an AS trigger group like the P99, that would be the ultimate CCW for me. Actually, if you can afford it, get both, you will not regret either one, my above comments pertain to a defensive/CCW pistol.
