I think I have found the culprit, and it is not springs ammo or cleanlines. Went to the range again today, and had another FTE.
Every time this happens the slide stays back so the good thing is you get to see what happened. I keep noticing how the case being extracted hangs up on the next round in the mag. This just doesn't seem normal.
The BD has a loaded chamber indicator.... well when you seat an empty cartridge between the extractor, and the little indent in the slide on the other side it seems the rounds sits awfully low. In fact when the rounds sits exactly where it is supposed to, the loaded chamber indicator does not potrude out the top of the slide because it is not sitting high enough. When you push the round up a little higher the rim of the case is not in the indent opposite the extractor. This would cuase rounds to not be fully extracted, and also cause the ejector to come in contact with the case at the wrong point.
Basically, the slide was not manufactured correctly. I am almost sure this is the reason for the problems. Because the empty case does not get caught by the indent opposite the extractor, it comes in to contact with smooth metal, wich cuase the case to get hung up in the ejection port in one way or another. It doesn't happen with every round, but I have put nearly 500 rounds through this thing since I've had it, and have not gotten through a box of 50 without a FTE. In fact... today was the first time that I only had one FTE with an entire box. Also I did not use WWB. The enhanced strength extractor spring may masked the problem, but I think at this point that there is a manufacturing defect.
I find it hard to believe that the orginal owner never had this problem. I have cleaned the weapon 3 times, scrubbed the chamber, and used about every type of 9mm ammo that I own. This can't possibly be an ammo issue, and if it were I would never have another CZ.
The only thing that determines me to fix this gun at this point is its accuracy. The accuracy is unbeleivable. This thing blows my XDm out of the water when it comes to putting rounds in the right place. The problem is in its current state it is worthless as a self defense piece. Every time I get an FTE I have to drop the mag.
