Just like 1911 - push firing pin all the way in, slide out the firing pin stop and carefully (it will fly out under the spring tension if not careful) remove the pin
Yeah, it does take some patience to wade through all the junk, but there's some really good ones there.
It's something worth doing when there's nothing good on tv.
Sid,
I have a pretty cool article on some history on the cz27 and some instructions w/pictures on field stripping and detail stripping that might help you. PM your email address and I will send them to you.
