CZ KADET .22 LR 10 RD FACTORY MAGAZINE 11601.
The CZ 75 Kadet magazine will fit flush with grips of the full size CZ 75. It can also be used in the CZ 75 compact models including the P-01, P-06, PCR that have the .22 Long Rifle conversion. However the full size CZ Kadet .22 LR magazines will extend below the bottom of the compact grips of those models.
The CZ SP-01 or Shadow Kadet uses the polymer magazines (11612 or 11613). The CZ 75 Kadet uses the metal magazine, CZ 11601. If your Kadet came with a metal magazine this is the correct. If you have the CZ SP-01 or CZ Shadow that comes with the polymer magazine, you need CZ 11612 or 11613.
