I read all the internet hype and bought a 75B 10 years or so ago. Liked it enough at first to also buy one of the Tactical models with a green frame. The machining looks like a bunch of high school kids with coarse files worked on them and the triggers felt like they were full of sand, but they were better than average in accuracy. Within a year they both started giving problems, as did the 3 my brother bought. After replacing every spring in every gun as well as all mag springs they were again acceptable, but I could never trust one again. I sold all mine and have no regrets.
In my experience if you want a range toy, and spend some money upgrading them right out of the box they are acceptable. But by the time you get them reliable, and get the trigger up to par, you have not saved any money over a better gun out of the box.
They are not on anyones list of good personal protection guns. Long term reliability is just not there. The slide inside the frame seems to increase malfunctions and makes clearing them much harder. The DA trigger pull is one of the industries worst, and the SA pull will never compare with a gun designed as a SA like a 1911, or BHP. Same with the location and operation of the safety. No where nearly as well designed as the 1911 or BHP.
Combining the qualities of a SA and DA into one gun probably seemed like a good idea at first, but the end result was the worst of the 2 designs, not the best. Do an internet search of CZ malfunctions. You will find an amzing number of hits. Pretty telling when you consider how few are sold. I wouldn't be surprised if Glock doesn't sell 10,000 guns to every CZ sold.
They are over rated and overhyped by a handful of guys on the internet. In the real world they are simply ignored by people who actually use a gun for more than a range toy. There aren't more than 3-4 CZ pistols for sale in every gunstore combined within a 75 mile radius of where I live. I haven't seen a single pistol at the last 3 gunshows I've been to includiing the largest in the Atlanta area.
If you want a SA, buy a quality 1911 or BHP. If you want traditional DA/SA, buy a Sig, S&W, or Beretta. If you want plastic striker fired buy Glock or M&P.
