I have no experience with the CZ-40. But every experience I've had with CZ has been really positive. I'm a huge CZ 75 honk, and have come away extremely impressed after shooting various other CZ pistols, bolt rifles, shotguns, and a couple Dan Wesson 1911s.
My experience is that they offer very high quality products at reasonable prices. The three metal framed, high capacity, full size service type pistols that impress me the most are the Sig P226 ($800), Browning Hi-Power ($900), and CZ 75 family ($500-650). I have all three. Regardless of price, I actually prefer the CZ.
