Congrats, Peter, on getting out with the new pistol. I have somewhere around 40k+ rounds through a Kadet on a 75B frame converted to SAO. It is my bullseye match pistol. A few things I have found that may be of benefit to you.
1. Use oil on the rails, not grease. On the .22, you don't need the extra lubrication and certainly don't need the viscosity of the grease.
2. Don't use a hammer spring lighter than 17 lb. Your factory spring is good.
3. Take a look at the big hole at the breech face for that firing pin. Rimfire gunk fills up that hole after a few hundred rounds and cushions the firing pin strike, causing misfires. Carry a dental pick with you and pick that crud out if you have a misfire. Pick the breech face and under the extractor while you are at it. When you clean the barrel, remove the firing pin and clean the firing pin bore.
4. CCI rimfires are a little harder than Norma and I will sometimes get a misfire on a cold day with the CCI ammo. I've pretty much standardized on Norma Tac22 and Norma Match for my Kadet, due to the 100% reliability with a 17# hammer spring.
5. When cleaning the barrel, be very careful not to bump the ejector. It is very brittle and will literally snap off if you knock it with a cleaning rod or a tool.
In my opinion, the CZ Kadet for the 75 series pistols is the best mass production .22 conversion available. I wouldn't trade mine for anything and have no plans to ever buy a "real match pistol".
There are more videos here on the Kadet than anyone that isn't bedridden has time to watch.
