I own five CZ 75's and 85's as well as a 97 in 45acp and I love them, in my humble opinion they are the BEST 9mm semi auto pistol ever made. As good as anything Sig or HK makes.
I know thats a big statement but I think it would be hard if not impossible to prove me wrong, for durability, accuracy, ergonomics, price and just plain old good looks they are at the top of my semi auto list.
On all 5 points yes on durability it's not hard. They are reliable but not to that extent. HK for instance guarantees nothing need to be changed or replaced for the 1st 100k rounds. A few years ago CZ had problems with the slide stop breaking and seizing the guns. It was fixed of course.
They don't do too well with high round count in class settings without mods. The fact that they include, or at least included, 5 (FIVE) extra slide stops with their competition guns should be a clue.
I had to borrow this from another person who put it much better than I could
"I think a lot of people are taking certain things out of context too.
I, please note, i, believe that the aforementioned instructors are making those statements based upon one thing alone and that thing is the question of why?
Why go with a CZ for a defensive pistol when you could get a Glock or any other "wonder nine" that will last you arguably twice as long, is easier to work on and is WAY lighter.
Parts are abundant for the modern polymer service pistols, they're all relatively proven at this point so again, why? Just to be different? There is nothing interesting, entertaining or rewarding about being different if you're buying a tool to defend your life with.
Go with what works, learn to shoot it well and call it a day.
Now, conversely, IF you want a toy to play around with, if you're looking for a competition gun then there is absolutely NOTHING wrong with a CZ as they are FANTASTIC guns and offer many advantages and very few disadvantages.
Glocks are popular for their simplicity and simplicity is good when it comes to tools."
