I carry the 19 and like it.
I bought a p07 two weeks ago and finally had a chance to fire it. Biggest difference is the Cz has a lot of trigger up take before it goes off. Not a bad thing unless you compete in contests. You don't notice it when firing.
Weight is about the same for both. Other than safety set ups, they are both great.
I put four hundred rounds through the Cz with no malfunctions, so it is good to go after I tested my carry ammo. Fed hydro shocks and hornaday tap. The Cz shoots 4 inches high with 115 gr ammo but hits dead center with 124 gr at fifteen yards.
Really, I feel fine carring either gun but I think my next gun will be a Cz. Possible an omega or sp1.
Found out the Cz fits my summer special II from milt sparks that is made for the hk usp45c. Happy about that.
