You could easily dispute that as well. The 1911 is for the most part only cloned here in the USA. Every other contry that allows even restricted gun ownership makes clones of the CZ-75. The CZ is a world gun - the 1911 is an American fetish.
I would venture a guess that IF there are actually more 1911 in the world than CZ-75 it is only because so many Americans own multiple guns.
This is very true as well. I also own 3 1911s and really like the platform and it really is America's gun. But the CZ is world class for sure.
