Hi,
I have been thinking of a sub-2000 but I do not have any of the handgun models that the magazines come in. I do have an Armalite AR-24 which I can use slightly modified CZ-75 mags. I can make a new release tab to catch the mag but it needs to be close to the existing notch position in the current mag.
Could anyone who has a sub and a CZ, please compare the two mags for the catch position and let me know if they are within a 1/16" of each other.
Paul
