RE: CZ Clones.
Generally speaking, there aren't any.
The earliest Tanfoglio guns -- in the '80s-- were clones or near clones, but as time passed, they made more and more changes to design details, so that they Tanfoglio guns were no longer clones. Its been quite a few years since anything but some recoil springs and magazines would interchange between a CZ and a Tanfoglio-built gun. (CZ recoil springs have a smaller diameter than Tanfoglio springs, so they swap in one direction only.)
The Tanfoglio-based guns have a slightly better firing pin block system that does affect the trigger pull as much. And newer Tanfoglio guns did away with the magazine brake, changed the hammer spring design, opened up the rear of the extractor channel to keep gunk for impeding extraction, etc., etc.
Many of the changes were done to speed/simplify production.
Many of the guns made in Turkey and Israel started out as license-built CZ-pattern guns, but they've also changed over the years... starting, most of them, with the Tanfoglio version of the CZ design. Some of the latest Turkish-made guns seem to have incorporated features of both the CZ and Tanfoglio pattern, but they all look and feel like CZs in the hand. (Except for .45s, where some of the Tanfoglio-based guns are a bit smaller.)
They're apparently ALL good guns, so the biggest issue is service. If IWI offers that, and if you have problems with some of the Turkish-made guns, and can get them fixed, you're good to go!
Some CZ lovers think that the early Baby Eagles had a slight ergonomic edge over the original CZ. I don't know if that's still the case. (I found the redesigned slide of the Baby Eagles ugly, so I never went there.) Some of the early TA models also had slide-mounted safety levers, too, which turned me off.
