I just ordered a pair of walnut grips ($55) for my CZ-83 from the CZ-USA store, and a couple of the recommended spacers to go with them. They have been on backorder for a while.
Also, I modified the front sight to take a little Hi Viz Spark ll front sight. It is a small green plastic light pipe, intended to replace the front bead on a shotgun.
Couldn't figure out how to add the pic...
