Does the POLICE version only take 10 round mags or do they also take 16 round mags? ---Reason I ask is because there is one here locally with a box and 2 mags and both mags are 10 rounders, which came from the factory. I see that this particular version is no longer in production, or at least with the "POLICE" rollmark on the slide...are not these just regular CZ 75BD's anyway?
