well the comparison is harder than you would believe..
both are clean and crisp..and have short resets..
a slight amount of camming in the cz..
The straight back pull of the 1911 will win every time if you are judging the 2 on trigger pull alone. Even a finely tuned CZ will not beat a production 1911 like the STI and getting it to that point will cost you more than the OPs budget.
