I have a pre-B CZ-75. I've been looking around for awhile now at different gun stores in the Portland area and the gun show at the expo center but I can't seem to find a pre-B 15rd CZ-75 mag anywhere. The 16rd mags fit and feed fine, but they are a little sticky coming out. I don't have many 19rd mags so I use them at IPSC and just drag my pinky down the grip to make it come out but drop-free would be nice. 19rd SP-01 mags fit perfectly and are drop-free, but they have a grip extension of about 1cm that can cause my shirt to ride up when I'm carrying IWB and sit down or bend over. I would like at least one original 15rd mag that will be drop-free in my gun. Does anyone know of any dealers around here that have a lot of CZ stuff I could check out? Thanks!
