CZ 97b question

[greystonedog]

just got my new to me CZ-97B.
On the left rear between the safety and the beavertail there is a hole in the frame, can see a vertical pin inside. What is this hole for? Am I missing a cover for it? Thanks

I have a question too. Why is this post here?

Never mind, I'll move it.

This is a retainer/lock for the hammer pin. Its there on all CZs including CZ 75s

The Omega system is totally different and the hammer pin is retained internally by a slot machined in to it which the disconnector drops into and locks in place. The traditional CZ 75 as well as the 97B/97bd actions all have the pin you asked about.
