Hi All,
I was cleaning my CZ 75B in .40 S&W and mucking about the magazine well with a cleaning rag, AKA an old sock, when I hung the rag up on a piece of spring wire.
Taking to the internet, I discovered what the spring was and was able to push it back in place under the transfer bar. Phew! I'm one of the people who started out with a 1911 and can take it down with out much fear. I am too new and over sighted now to mess with the CZ but I do love it.
Best,
Rob
