CZ's are over rated and overpriced for what you get. If you want a gun for range use they are above average in accuracy, way below average in durability and reliability. I'd never use one as a personal defense weapon. Range toy only. And then only after every spring in the gun and every magazine were replaced.
There is a reason they are only used by a handful of 3rd world countries for LE and military use. When tested side by side with Glocks, Sigs, S&W, and Beretta they just can't keep up.
They have a few internet fanboys who make a lot of noise creating the illusion they are popular. I couldn't find a dozen of them in every gunshop within a 75 mile radius of where I live. Going to the largest gunshow in the Atlanta area wouldn't net more than 3-4 CZ's at the entire show.
Do an internet search of all the gun forums and you will find more posts about CZ problems than any other brand. Quite an accomplishment considering how few they sell. Wouldn't be surprised if Glock alone didn't outsell them 10,000/1.
I had a few CZ's at one time, bought mostly because of internet praise. Liked them well enough at first, but quickly found out why it is often called the errornet. Sold mine and wouldn't want another.
