I have a new CZ75B that I dearly love except for the ring hammer. I've seen pics of the retro 75th Anniversary CZ75 with the spur hammer and I'd much prefer that hammer. On my Browning HP swapping to the spur hammer was not a problem but apparently it is for CZs (according to my search on this forum). Anyone know of a source for spur hammers (new or old) that will fit the 75?
