Got a new CZ-75B a few months ago and have probably put >500 rounds thru it so far. Everything is stock, i.e. no spring or sight changes, etc. I've got both factory and Mec Gar mags. The State Politburo only allows 10 round cap. I mostly use a Maglula speedloader, but sometimes load the mags the hard way. Anyhow, I've had at least 5 to 6 Failures to Extract on my last two outings at the range with both Winchester and Browning 115 grain FMJ rounds. It happened with both brands of mags and didn't seem to matter whether I used the speedloader or not. I've heard nothing but rave reviews about the 75B so this is a bit troubling. Anyone have any suggestions? I was thinking about calling CZ for advice. Hopefully, it doesn't have to go in for service. Thanks in advance for your replies.
