The cost of the magazines for the CZ P series is a common complaint. If you hang out on the CZ forum it's apparent EVERYONE is waiting for CZ to give Mec-Gar the green light to start producing them under their own brand name.
That aside, the P-series pistols are amazing. For a time I thought they were 'underappreciated', but sales numbers from CZ show they sell just about every one imported into the country and they often go on back order. I had to trade a SIG P320 to get my used P-07, and I think I got the better part of the deal.
