cz told me that their handguns made overseas were manufactured so the magazine would not fall out like the ones from the states. they also told me they would (bend the release spring or whatever so that it would fall out). it still hangs up. i feel that the magazines fit too tight because there is no play when they are in the mag well like my other handguns. this may not be an issue to some, but i shoot idpa at times and and the mag needs to fall out of the way. also, you have to think about getting into a situation were you are defending yourself, you don't need to be fighting the magazine. just my 2 cents.
