I purchased the Kadet conversion kit for use with my CZ-75. Beautiful, all stell construction, and provides excellent plinking but not bullseye shooting accuracy. Some people have complained about unreliable firing pin strikes but mine has functioned flawlessly with most ammunition. My unit seems to prefer either European ammo like SK Jagd, Wolf Match Target or ammo with little outside lubrication. My unit had problems reliably feeding CCI-SV but would handle SKJagd, Wolf Match Target and federal Copper Plated ammo or Federal; 711B with utmost relaibility. It's a real fun unit to use.
