I had the pleasure of meeting up with and sharing a lane at my local range with THR member Chaim a little over a week ago, and he brought along his CZ-75B. I had never seen a CZ in person, let alone fired one until then - he let me put a few mags through his, and I knew at that point I'd be getting one.
The example he owns, by his admission, has over 10k rounds though it, and the only discernible issues I could find with the gun was that the grips were slightly loose.
So, long story short - I'm no CZ expert, but they seem pretty well worth it to me.
