Yesterday I got a CZ form a Forum User, Was A Great Deal!! so I jumped on it. I bring it home and Disassemble for cleaning and inspection, As usual the cast firing pin showed some stress is to be expected. In another trade I had a Firing Pin from BCA INDUSTRIES http://www.gunpartswarehouse.com/cz52.htm Wow!!! compared to the original cast pin the BCA INDUSTRIES was by far better quality and simple to install. They also guarantee it for 2 years for only $18.50 the machine quality and fit is very good. Thanks again to the seller for such a great pistol it fit's nicely in it's new home "my safe" were it will live till I die.
