As an update to my earlier posts, finally was able to get some action out of CZ almost three months after the fact. They ended up replacing all together the 28 Gauge and repaired the 20 Gauge. Repair sheet indicated all they did to 20 Gauge was reangle the searing pins. Not sure if I have that right but gunshop said thats what it was and that CZ had test fired gun several times and it worked flawlessly. Thay may be the case, however, my problem was intermitten but was progressing in instances. Don't know if what they did will fix it but first time it misfires it is going back post haste.
The replacement 28 Gauge had no reason included when they shipped it. They sent it with no explanations what so ever. Don't ask don't tell policy I guess. Was worried that what they would send was some crappy gun with yucky wood since I had hand picked both guns and tried my best match the wood. They actually sent me about the same color wood and the stock had a lot more character with a kind of scrolling grain. So I was happy with the wood. The most interesting thing that I noticed immediately other than wood is that the new gun did not have the same style manual safety that I have seen on every other single selective trigger CZ model gun. The new safety is Baretta styled and has a button that is embedded in middle of safety that slides left or right to choose barrel. Instead of an H pattern or U pattern the new safety is up back only. It is also much smoother to operate. To this point if works I am happy with replacement gun and glad 20 Gauge is back as well. However, if this is going to be the new way CZ produces safety would prefer that they would have replaced 20 gauge as well.
Have not been able to go shoot either gun yet. Wether they look good or have some feature changes my biggest is concern is if I pull the trigger they go bang. If I don't put a shell in the chamber, that is my fault, but when I go shooting I always am certain what's in my gun. I make it point to neverr dry fire. At any rate I believe there is a severe shortage of new CZ guns on the market and I believe they are waitng until existing inventories are depleted before offering new and improved models instead of a recall since problems may be intermittent. Word has it local reps are told not to order any new guns since they have a production shortfall. That may or may not be the case but something is up. The gunshop I went to was leading retailer of CZ guns in US last year and they can't get guns. CZ rep was actually in gun shop when picked up replacement gun. He was impressed wth new safety operation and had no idea they were changing it. He speaks to them regularly and there was never any mention of feature changes. I sincerely believe CZ recognizes they have a production quality and capacity problem are trying to fix it gradually with some better components and quality controls. This is just my conjectue and would love to be proven wrong since my 20 gauge is still the orginal version but I'll bet they just didn't send the 20 gauge with new safety unless they had to. I don't know if I am a victim of kicking a problem can down the road with 20 gauge or if they dressed a 28 gauge with nicer features but did not fix problem. Time and use will only tell for me unless someone with other information becomes available.
