Well, I'm sorry if you fellas do not feel satisfied with your rifles. I now own a CZ75B in .40 cal, and a 527 LUX in .223 caliber. Both are outstanding designs and function flawlessly. The trigger on the rifle is a dream, truly a dream. The set mode takes some getting used to, but the standard trigger breaks cleanly, and the rifle shoots where pointed.
My next one will be one of the .22 long rifles, though I am not convinced that I'll use the set trigger feature of the 453, so I'll probably get the 452. Either would be nice.
I have not had to call on warranty or anything like that, so I cannot comment on customer service, other than to say that when I ordered rubber grip panels and night sights, they were in my hands by the end of the week. Pretty prompt service IMO.
YMMV.
Regards,
Stubb
