Don't knock florida1098 for preferring Glock. He never said it was best for everyone, just that it is what he prefers and what he will buy.
The only service pistols I'll carry are also Glocks, because in my opinion they are the best design on the current market. I acknowledge that there are many other good guns on the market, but I will only buy Glocks (in service-type pistols).
And CZs are hardly infallible. My experience is that they are very reliable pistols, but not quite as reliable as Glock.
