I have owned many CZ's, and carried them. I have had a few problems, as is expected when you own seven or eight of the same make of gun and shoot thousands of rounds out of them both in practice and competition. Other than the Glocks that I now carry (and have far fewer rounds out of them), the CZ's have had fewer malfunctions than any other semi-auto that I have used, and FAR fewer than the 1911's that I have used, which seem to be the gold standard for many people. I stopped carrying my CZ-75Bs and my .45 cal EAA Witness for one reason - they can get very heavy. The CZ-75B is NOT tactical Tupperware! The CZ-75 P-01 is a bit more comfortable to carry than the -75B, but I do not particularly care for decockers.
I carry a Glock 21SF now, or a Glock 20SF if I am in the field. They are certainly NO lighter than a CZ-75B. However, I like the 13 rounds of .45 ACP carried in the G21SF (the EAA only carried 10, and you could not find magazines without ordering them) and the 15 rounds of 10mm carried by the G20SF (CZ does not chamber the 10mm, and the EAA in 10mm has the same availability problems as the .45 EAA). Even though I have switched to the Glock, I still maintain that the CZ is better built, better feeling, and more naturally pointing than the Glock, and I would still recommend it as a carry pistol.
