Just bought a Kadet kit for my CZ-75B at a local dealer. $229 with two mags. It fit on my CZ-75B Mil without any filing or fitting and is very tight.
I took it to the range yesterday and put 50 rounds of Amercian Eagle High Velocity and 200 round sof CCI Mini Mags without any FTF's or FTE's. Function was perfect and accuracy superb! Almost equal to my Riger Mk II 5.5 inch bull barrel and its a full size combat gun. Great practice for a lot less money, even though I do reload for 9MM. I switched slides and put 100 rounds of 9MM downrange. Fantastic! My Rugers will probably be collecting a little dust in the gun safe now. I am a very staisfied CZ customer. Next, I will try it on my PCR!
