I have a PCR. I looked at a Po1, and it seemed almost identical other than the rail. . Different rear sight , and according to the literature, the Po1 has interchangeable parts that dont need fitted. I kinda have mixed feelings on that. I have heard or read no complaints on the Po1, and I certainly cannot complain about my PCR. Its certainly a keeper. Truth be told, my most accurate 9mm. Any CZ stuff just seems flat out impressive and addictive as hell. . So I'd say its 50/50.
