Owners report that the single action trigger pull is somewhat heavier then the original Python but accuracy is as good..... and in some cases better then the original Python.
.
While I cannot confirm the single action trigger pull comparison with the original Python, my new manufacture Python's single action trigger pull is heavier than my S&W 586 and 686 pistols.
The double action pull on the Python is quite nice when compared to the S&W's. Apologizes for not putting a trigger pull gauge on them.
I've put a couple boxes of mid range ammunition through the Python and have been pleased with it so far.
