Just an update on the 'Factory CZ' magazines from CDNN: just received one today and it is one of the fake/junk 'mfg CZ' mags. Interestingly it came in a sleeve saying it was 'Factory CZ'. Caveat emptor. I will try it this week as just a range mag & hopefully it will work ... I've been buying from CDNN for many years and this is the first time I've been skunked.
