I've seen on several threads on this and other boards that CZ magazines don't drop free when the mag release button is pushed. I just dug my CZ's out of the safe and checked. On my CZ 75 BD (9mm), 75B (.40 S&W), and my PCR all magazines dropped free of the mag well with the push of the mag release button. I only have factory mags, no aftermarket. Does anyone have a CZ that retains the mag? Just curious.
