I blew up a couple CZ52s in 2000 and did some investigating.
I bought an extra 10 CZ52 barrels from Century.
We tested those on an RC hardness tester at the Jet Propulsion Laboratory [that sounds cool, but I was just too cheap to buy a tester].
CZ52 barrels have very thin section of the chamber wall over the roller pin relief cut. That is where the splits form. The metal can be as soft as RC25.
But, the aftermarket 9mm barrel is RC47, which is like a modern Kel-Tec barrel.
What does it all mean?
The 9mm barrel is ~ twice as strong.

The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
