chaim, can you elaborate on your earlier post? What kind of problems have you seen with CZs, and which models were affected?
My friend on the internet's gun (I met him on the net, we became real world, though long-distance, friends in the couple years before he passed) was a 75B (actually, 2). I don't remember the specific issues anymore, if they were "only" ejection and feeding issues or if there was something more (he passed away a couple years ago so we haven't discussed it in some time). I just remember him being very frustrated with all the work to get it right (sending it in to CZ-USA on more than one occasion), then being extremely frustrated when CZ saw how bad his gun was and replaced it, and the replacement was no better. He eventually got it working well enough to be a range gun (he loved it when it worked), but never well enough to trust to defend him and his wife (he ended up buying a S&W 910 for that purpose, it never hiccuped, and prior to that he used his S&W model 10).
My best friend has an 85 Combat (a nicer version of the 75B). As far as I know it has just had ejection and feeding issues, but it has had quite a few of them and his fixes (springs, checking for burrs, polishing select parts, and other work I'm not sure of) have done nothing except slow the problem (it is still an issue, just not as often).
My gun is basically reliable. I stopped counting at 5K rounds so I expect some issues. However, even it has feeding and ejection issues more often than I'd like and an occasional failure to go into battery (on average over its lifetime I've had 1 hiccup every 3-500 rounds, lately, more like one every 100-200, and last range trip, one every 2 or 3 mags). I change the springs regularly, but the increase in issues
may signal a need for new springs. It is a 75B.
I had a 40B which was 100% (if I remember right, I stupidly sold it about 4 years ago- Spot77 is the current owner, and last I heard he is quite happy with it).
On the internet you hear mostly about feeding and ejection problems on the 75B and 75B based guns (that's pretty much all CZ makes). In many cases it may simply be a result of CZ's use of underpowered springs. However, not all the problems seem to be solved by replacing springs.
All that said, I don't necessarily have a problem with CZ (I know my posts may sound like that sometimes). I just want to bring some sanity into the room when all the CZ-fanatics (I used to be one) start in, sometimes claiming the CZ to be better than such guns as SIG and HK. When you get a good one, they are very good guns. You may be a little more likely than average to get a lemon (my experiences along with internet observations suggest that to me), but most of their guns are just fine. If they improved their QC a little to stop some of the problems, put in better springs, and improved their fit and finish of the interior parts, they indeed would be in the same league as SIG, HK and the better 1911 makers (but then, the price wouldn't be the bargain it is).
As they stand now, I don't consider them competition for guns like SIG, and if you can afford the better gun, get it. I consider them competition for Taurus, Ruger, and other good but more budget oriented guns (they may be good guns, they may be nice guns, but some corners are cut somewhere). For reliability they probably are very similar to Taurus (good guns, they could improve their QC, but if they did they wouldn't be the bargains they are), and I love Taurus. I defend Taurus all the time, I try to put some reality back into CZ discussions. Why? Because you hear Taurus being attacked quite often and CZ being lauded as the best thing since sliced bread, when in reality both are good guns that could be better- in both cases I try to bring (sometimes emotional) discussions back to reality.
I used to be a fanatic and want one of nearly every variation. Now that I'm more down to Earth about it and consider CZ to be an average gun, I don't really want to add much to my CZ collection. One 75B is enough, I don't need a 75SA, 85Combat, etc. They aren't so well made and reliable that I need more than one of the basic design. For ergonomics I'd rather have a 1911 or Hi Power. Still, I would like to find a LNIB condition 40B eventually to replace the one I stupidly sold, and I'd love a PCR. The P01 may be their best engineered gun yet, it just doesn't do it for me (I don't like the rail on that gun).
