CZ may well have seen examples that I have not, but in all the images I have seen of pinfire breech faces I've never seen one with cuts in those positions. All I have ever seen have had a uniform vertical "cut" running from the top of the breech face straight down towards the center.

I've never seen one with cuts in those positions, and really cannot rationalize any reason why a pinfire would have "cuts* in that position.


May God bless America and those who defend her.
