Hiya Kleab, you can find a Kadet and a Kadet kit, just need to keep an eye out, but I can see that the market for a 600ish .22 handgun and cz's decision to discontinue as just a business thing, think the 83 also is a done deal. I use my Kadet 2 kit on 3 frames, 2 of which had czcustom trigger/hammer tuneups and no one ever mentioned bout your comments. I was having the lite strike issue tho, which Eric at czcustom assured me had everything to do with the quality of ammo I used (federal multipak) and if I went to CCI the problem would dissapear. The forum pointed me to the hammer springs, and went from the 13lb to 17lb and only then did the problem dissapear. Thanks forum, again for savin me big $$$.
Kleab, I did have the FO added to the Kadet kit and feel it was a good move for my 53yr ol eyes. I also came across a couple european cz's in .22 that we dont see much of here, one of them appears to be on the 83 frame. Hope ya find one to enjoy. Be well.
