I had one and it was a very good gun, it just didn't quite do it for me.
It was 100% reliable, in fact it was my only auto that never had a hiccup (wait, it
might have had one or two in break-in the first hundred or two rounds, I don't remember anymore). It is made to CZ quality standards, which are very good (nearly up to the next class level- Beretta, SIG, etc). At first I didn't think it was particularly accurate (average, but not to CZ standards) but then I found that it is sensitive to bullet weights and with 165gr. bullets instead of 180s it lived up to my expectations. The rear sight did come loose but not bad enough to hurt function (it was still decently accurate) and it was nothing that locktite wouldn't fix (apparently the stuff comes in different strengths, ask around for which color loctite is for perminant jobs). The price is incredible. At under $400 (well under in some localities) it is probably the best bargain in .40S&W guns out there.
What didn't I like about it?
It was a .40. Not to start caliber wars but I'm a .45 and a 9mm guy in autos. I feel that 9mm can do just about anything a .40 can and when I want more the price difference isn't really there so I may as well step up to a .45. Maybe if I didn't already own a .45 I might not have felt that way. Also the .40 doesn't have the selection of cheap practice ammo 9mm has (though if Walmart came out with the Winchester White Box value packs for ~$15 a few months ago instead of now I'd probably still own the gun instead of selling to Spot77).
It is a compromise gun. I now have enough guns that I may as well have dedicated range/full-size guns and dedicated future CCW guns (for when I'm in a CCW state) and this one is kind of a compromise size where it tries to be a little of both. It is aluminum alloy so it is lighter (and slightly higher recoiling, at least in theory, though balance and feel is good) than an all steel gun so it isn't quite as controllable, yet it is 28oz so it isn't that much lighter than the full-size steel framed CZ 75 (~33oz). It has a 4" barrel so it does lose some accuracy and sight radius v. a full-size but it isn't
that much shorter and it is very thick (much more so than my full-size CZ 75). For me the length could have been lived with (4" is noticably shorter then 5" after all) and same with the weight (you do notice 5oz after a period of time) but the thickness took away any advantage it might have had for potential CCW over my full-size options (the much narrower CZ 75B or 1911). It is simply too big and heavy to be a great CCW and too small and light (for the caliber) to be a great range gun, though it certainly is a good range gun and would probably be an acceptable CCW.
So I do think it is a good gun and great bargain. If you are in the market for a mid-sized .40S&W it is a good choice. However, it wasn't for me and I sold it to Spot77 here on this forum. Again, it was close enough that with more cheap practice ammo options I might have kept it and the new Value Packs of Win White Box out there might have caused me to keep it after all. Also, it was a good gun that I liked and I'm half tempted to buy another even though it got far less use than my other guns (this temptation only started when the cheaper ammo at Walmart came available- I wonder what I'd have to offer Spot to get the old one back, hmmm, he does want a revolver right now and I know a couple places with some really nice used wheelguns...
