If they are so unreliable and prone to failure how did the P-01 get a NATO stock number?
http://cz-usa.com/press-release/cz-p-01-gets-nato-approval-the-next-generation-of-perfect-pistols/All the 75 variants run essentially the same internals. Sure there are different frames, springs, barrels, grips, etc... but they all share the same design. This design has been combat tested, competition tested, self defense tested and just plain run through it's paces more so now than ever. Sure things do fail and there is bound to be a lemon that comes off the manufacturing floor every once in a while, but every manufacturing outfit has to deal with this. There is no such thing as 100% yields (trust me I know I work in the medical device manufacturing industry). Sure they could add more QC to the process to mitigate that risk but then it would translate to increasing the cost of the item and I for one don't want to see the cost of CZ's increasing! It's how the company deals with the lemon that separates themselves from the pack. CZ-USA has shown they are willing to make it right with few exceptions.
Every failure (a handful over thousands of rounds) I've experienced with my CZ's was my fault, either reloading issues or my own "gunsmithing" related learning. Do I have spare parts, you bet I do. I shoot competition and don't want a simple failure to end my day at the range. If I was really committed I would have a spare gun on hand.
Go shoot them and find out if they are unreliable for yourself. Keep detailed records so you know exactly how many rounds to failure. I'm sure you will be pleasantly surprised.
Oh and I don't always carry, but when I do... I prefer CZ. Stay thirsty my friends.
