I have over 2000 rounds through a P-09. All I've changed so far is the hammer spring, firing pin, and firing pin spring. Trigger pull is very good now for a service gun. About 3 lb 2 oz in single action. Still has some creep to it, but very good compared to most service guns. I am another shooter that did not ever expect to like a polymer gun. I can't stand the grip angle of a Glock, and love the grip and ergonomics of the CZ 75B so the P-09 was a good choice for me for my first full size polymer gun. I am very, very happy with it, even out of the box. Aftermarket parts are coming very soon to fix the trigger pull. When those are available and I install them and get a few rounds through the gun, I fully expect the P-09 to become my favorite centerfire 9mm pistol, even though it will take me a little more time to get used to the feel and sound of a polymer gun. I shot it well right out of the box, and very well after spending a little time with it. A very good polymer gun for me.
