Pat--
I came to the same conclusion about the CZ-75B that you did, and in short order.
The S&W 4006 is a very good pistol, even if made in the USA. There seems to be a tendency for some pistol enthusiasts to look down their noses at any American-made service pistol other than a 1911A1, and that is DUMB. I think highly of both S&W and Ruger service pistols, and have had nothing but good experiences with my examples.
