I’m late to the thread, but I believe it is a Torx T-20 (size).
I’m looking at grip options. I really like the look of the black AL grips it comes with, makes it a piece of art!
But I want a little thicker grips. Have looked at several, Cool Hand, LOK, CZ-USA - Honeycombs + Ovals. I saw some nice wooden grips that are handmade, in Hungary I think. Anyone have any other options, know a company hat stocks grips for the CZ 97 or has them on the list to make custom?
