One solution that helps is holding a handgun mostly Inside a large sandwich bag while removing tiny parts.
It can be done while easily viewing the necessary components through the bag's Opening. It will usually block any spring which jumps, in most directions.
And it certainly catches any tiny part which simply falls out.
Thanks for the warning on the lifter spring, but although I've disassembled both a Sig P6' frame and the frame of a S&W 6904 (thanks to superb videos), I have no reason to do any detail strip any CZ frame.
