My CZ-75B is a nice gun, but not without flaws. With less than 200 rounds through it, the nickel on the slide rails is peeling/flaking off. I called CZ with my concerns, and they said this is normal and expected, because something about the way they do the nickel plating. Supposedly whatever coating they put on before the nickel is not applied to the rails, which will cause some pistols to lose the nickel on the rails quickly. Has not affected function, and CZ says it will not, but it is definitely corner cutting, and nobody likes to see the finish gradually flake off of their gun, even if it is "normal".
Also, the triggers are pretty sloppy in general. I didn't understand this until I had more handgun experience, but the CZ 75B trigger is not very impressive compared to other guns, even those at or under the CZ price point. The Omega trigger system CZ's are better.
I can carry a full-size 1911 more easily than my CZ-75B. It is a thick, heavy gun, ill-suited for carry. It is, however, extremely accurate and has been reliable. Mine still serves nightstand duty.
I loved the size, weight, reliability and accuracy of the CZ P-07, but sold it because it was gradually wearing small holes in my body with its sharp edges, and the lack of quality holsters made for it made the problem difficult to remedy. The lack of an aftermarket for the P-07 in general was frustrating. Oh, and lest I forget, a month after I bought the P-07, the white sticky strip peeled off of the front sight for no apparent reason. Apparently a common problem. When companies go so obviously "cheap" on such an obvious part of the gun, I am the type who can't help but wonder what other small parts they might have cheaped out on.
Overall, I like CZ's, but I am not as "into" them as I was when I first got into handguns. As the prices continue to go up, they seem like less and less of a value compared to other $500-$600 guns. The P-07 makes a viable alternative to the Glock 19 when priced at $400, but if the price continues to rise, there is no reason to choose CZ over Glock/M&P/XD, especially once you factor in maintenance, parts replacement, aftermarket upgrades, and holster selection. Spare mags alone will run you $50 apiece once you factor in shipping costs.
I think I am moving out of my CZ phase, like a lot of folks seem to do once they gain a certain amount of handgun experience. They are good guns, but not the amazing steals I once thought they were. And their shortcomings become more apparent to me as I become more refined and discerning as a gun owner. I'm not saying don't buy them. I'm just saying don't drink the CZ "kool-aid". You aren't getting a $1000 gun for $500, so don't go into it thinking you are.
