I understand why people don't like this kind of thing with a new gun, tolerance stacking is off putting, but at the same time when you consider how many of the guns are made and how many of the parts are produced etc etc, it happens. It's possible CZ would warranty it, maybe. And yeah a cage is what, $30? But that doesn't always cure it, sometimes it's safeties, sometimes it's hammers, and other times it's sears. Like I said, if it's has a regular hammer, the money is better spent on a competition hammer and that might cure the problem. I've got 6 Shadows right now, 3 Canadian Shadowmates, the top ones, and 3 regular ones that have been upgraded with all the bits. My original Shadow the safeties used to be able to be put on when hammer down. But that's because I fit them with a Leatherman file in a dark lounge/attic area upstairs at the Althansky Palace in Znojmo, Czech, after getting them from Milan. Angus Hobdell and I sat there, drinking, and fitting them, well, I did the filing he just made crass remarks. I filed too much, on the sear actually, and that resulted in the safeties going on with the hammer down, I also took too much off the flat spot on the left side safety post, that the right side safety connects too, which resulted in that safety kind of flopping around. I replaced them and those are now my emergency backup backup safeties. I should just toss them.
As for round count, 150,000+ rounds through my original Shadow before it became a dedicated .22 and similar through 4 of the others. My new match gun only has about 30,000 rounds through it.
