I own CZ-75B, and I had a chance to shoot
it's U.S.-made clone P9 also.
It does copy most of the CZ75 features, but
overall quality of manufacturing, trigger
pull and accuracy are not as good as in
original CZ...Don't know about reliabily,
but when I shot it, there were no jams.
CZ-75B proved to be totally reliable when
original CZ magazines are used. Wasted
more than 600 rounds through it...Fun.
