Hello. Since the original post was written a while back, I've continued to use the Kadet conversion on a fairly regular basis with today being the latest session.
The pistol is in about the same form as when I did the original post.
The Kadet conversion is on the same CZ-75 Pre-B frame as before and still using the same parts as before. I've not kept records on this one but expect it has probably digested another 2000 rounds since the original post.
Today I fired 150 shots of Remington 38-gr. "Subsonic" hollow point ammunition. The Kadet has always shot that load both accurately and reliably. This session was no exception.
I did some one-hand shooting but primarily focused on trigger-control, sight-picture and follow-through today.
These groups were fired at 12 yards, standing and using a two-hand hold in slowfire. The 1-inch diameter "targdot" group at the top was fired at 20 times, ie: 2 magazines-full. The 2" diameter bullseye group consisted of 30 shots. (I meant to do 25 in each, but got distracted and had 30 in the lower target instead of stopping 5-rounds sooner!)
I have found the CZ Kadet to remain both reliable and the thing simply has not broken any parts nor does the recoil spring seem unduly light. The slide consistently continues to lock rearward after the last shot is fired and the LPA adjustable rear sight has held its zero just fine.
Because the sights remain stationary during the firing cycle, there is reduced chance of them not holding zero. These simply have not required readjusting ... other than when changing (some, not all) between ammunition brands.
I consider this one well worth the money spent to buy it.
Best.
